Decent dough poor fulfilment. 3 out 5 items missing

I had mixed feelings about my first order.

The pizza kit itself was good and the dough produced some nice pizzas. However, the fulfilment side of the experience was disappointing and left me questioning whether I would order again and it seems i'm not the only one.

When my order arrived, the mozzarella was missing. After contacting customer service, I was offered either a refund or a small amount of store credit, but was told they were unable to send a replacement mozzarella as it was a perishable item. I found this confusing given that the company main business model is to ship perishable items.

So i had to now freeze the whole batch of dough as I was unable to purchase mozzarella straight away.
But after eventually purchasing my own mozzarella and coming to use the kit, I discovered that two additional items were also missing: the Flour & Semolina Pizza Preparation Dust and the Pizza Peel Dust. This meant that three separate components had been omitted from the same order despite the company stating that orders go through a two-stage checking process.

Customer service did refund the mozzarella and later sent out the missing dusts once I reported them. The issue was ultimately resolved.

That said, the process took multiple emails, additional delays and a fair amount of effort on my part to obtain everything that should have been included in the first place. The product itself was good, but the packing and quality control let the experience down.

Based on the food alone I would have rated it higher, but based on the overall experience I can only give 2 stars. I wouldn't say they went above and beyond to help rectify any issues.

I suspect they are growing to quickly and are struggling to cope with demand. I won't be rushing back just yet and will be trying some competitors first.

Hi Ben

Hi,

We are incredibly sorry about this. We completely agree that missing three items from a single order is totally unacceptable, and we understand your frustration with the extra effort it took to get this sorted.

To be completely transparent, you hit us during a bit of a perfect storm. We have recently been transitioning to a new fulfilment service, which unfortunately coincided with a sudden surge in demand and a wave of staff sickness. While that explains how things went wrong behind the scenes, we know it doesn't excuse it. You should have received everything perfectly the first time around.

Our team has now dispatched the replacements for the missing dusts and refunded the mozzarella, and we genuinely hope they arrive safely and that the rest of your order is great.

We appreciate your honest feedback about our growth and fulfilment—it's exactly what we are working hard to tighten up right now. Thank you for your patience with us, and we hope the quality of the pizzas means we might see you back again once we've smoothed out these growing pains.

Best regards,

Team GBOF

Rude Customer service Awful!

I placed an Order of 5 items!
4 items arrived in good time.
However the order was short of the Pizza Peel dust and a leaflet or any instruction how to store and handle Dough.
Contacted GBOF by email to which I got a reply advising it had been forwarded on to a supervisor as this should not have happend with double checking method. To put this in context this is a £4.50 tube of Flour and I felt like GBOF was implying I did recieve.
I phoned GBOF and the owner answered the phone he was extremely rude and un helpful.
I will not be placing any further orders

Hello Paul

We appreciate you taking the time to share your feedback, and we are glad the main part of your order arrived in good time.

We are incredibly sorry for any misunderstanding regarding our email response. We completely appreciate that items sometimes do not get packed; it is a human packing line, and human error can happen occasionally. We would never imply that you received something you didn't. The reason we ask customers to double-check is simply because smaller items like the dust tube are sometimes wrapped up inside the protective packing paper to keep them safe.

We always want to make things right when we miss something, which is why we have already dispatched a full replacement to you and processed a refund for the pizza peel dust.

Regarding your phone call, while we aim to handle every situation professionally, you have omitted that you were aggressive and sarcastic, and that you swore at our team over the phone. We are a small business run by real people, and aggression and rudeness towards our staff will not be tolerated under any circumstances.

We hope that now the replacement is on its way and the refund is settled, the matter is concluded.

Best regards,

Team GBOF

Avoid, very poor logistics

Where to start. I have placed 2 orders with GBOF. First order we had shipping damage where the flour burst open, GBOF did resolve and provide a £10 credit to my account.
Second order was shipped too early despite me paying an extra £5 for a nominated delivery day later in the week.
This is where it all went wrong, they said they would refund me the second order, however the package was already in transit, ironically that parcel was rejected by DPD as the tomato sauce bottle was smashed in transit, packaging issues again.
GBOF offered to refund my transaction, however they refunded the first order for some reason and are now ignoring my emails relating to why they refunded the incorrect order!
The second order was for more money so it looks like I will contact my bank and raise a dispute against GBOF.
I would avoid at all costs and order from other pizza dough suppliers.

Hi Stephen

We never, ever send out orders with the intention that they will arrive damaged. While we expect our couriers to treat packages with the respect they deserve, we don't own the courier company and, frustratingly, we cannot control how they handle things in transit once they leave us.

We are a small, independent company trying our absolute best to provide an honest service. Telling people to "avoid us at all costs" over courier damage and an administrative mistake is incredibly damaging, and it's the kind of thing that drives independent businesses like ours under. There are real humans at the other end of these emails working hard to fix things, and a little patience goes a long way.

That being said, we clearly made a mistake in processing the wrong refund amount, and we are not ignoring you. Our team works through emails in order of receipt, but we want to get this squared away for you immediately.

Please contact our support team directly with your order details so we can fast-track this, correct the refund difference, and make sure your account is completely settled.

Best regards,

Team GBOF

DO NOT USE THIS COMPANY

Order was missing dough balls, sauce and garlic dip.🤦‍♂️

Absolute clown of a company as all the other 1 star reviews suggest.

DON’T ORDER FROM THIS COMPANY PEOPLE.

Reply to the companies reply.
There were three items missing from the delivery ( dough+sauce+garlic dip), one item- fair enough, but three!

Initial email contact with your customer service person also REALLY didn’t help as I was told that you could NOT send the missing items out but could give me a credit note🤷‍♂️ 🤦‍♂️, however after leaving this review it became evident that the ‘person’ I’d being talking to via email was Infact an ai robot that had given me wrong information🤦‍♂️, a real human eventually stepped in and sent the items out the next day (which I appreciate), The items have literally just been delivered and unfortunately the pre stretched dough has mold on it even before I’ve opened the clear, sealed package (I have photos).

So all in all a, really not a good service. Your adverts looked absolutely great, and I was really looking forward to using your products, however the reality was very disappointing.

So you lose a customer and I lose the pizzas I was looking forward to.🤷‍♂️

Hi Mark

We are sorry to hear that your order was missing items. Having components left out of a box is completely unacceptable, and we understand why that’s frustrating.

However, we are a small team of real humans trying our best to provide an honest service. Mistakes do happen, but calling us a "clown of a company" is completely uncalled for.

If you contact our support team directly with your order number, we will gladly look into what went wrong and get this resolved for you.

We understand our order was successfully processed and dispatched to you.

Best regards,

I ordered Neapolitan and Gluten Free…

I ordered Neapolitan and Gluten Free dough balls. Order arrived and it contained sourdough and Neapolitan - NO GF balls. Tried contacting them but was told that I had ordered the wrong balls. Which I know I didn't. Also - as other have said - the packaging was split on some of them and had leaked over the others.

Hi Catrin

We have thoroughly checked our system regarding your order, and we can confirm that you did not order Gluten-Free dough balls. We can only dispatch what is on the digital invoice, which is why our team advised that the order placed was for our Sourdough and Neapolitan range.

However, we are incredibly sorry to hear that some of the packaging split in transit and caused a mess inside your box. We never want our dough arriving in that state, and we want to make it right for you.

Please contact our support team directly with your order details. We will gladly get the split items sorted out for you and ensure this is resolved.

Best regards,

Great product, let down by packaging.

The product is great and the pizzas are fantastic.
However the plastic bags they were delivered in were split, wasting some bals and the box had been destroyed on delivery. So I had to bin nearly 50% of my order. Very sad and wasteful.

Hi Larry

We are really glad to hear you love the product and that the pizzas are fantastic, but we are absolutely gutted to read the rest of your review. Seeing nearly 50% of your order go to waste because of a destroyed box and split bags is heartbreaking, and it's definitely not the experience we want for our customers.

Please could you get in touch with our support team directly? If you can drop us an email with your order details, we will get on it straight away and make sure this is fully resolved for you.

Thank you for letting us know, and we look forward to sorting this out for you.

Best regards,

Disgusting attitude.

Very, very poor service!
Paid to nominate my day of delivery. Items didn’t arrive, fresh dough, meat & cheese. Asked for a refund as DPD said they would be bringing it the next day after being out of refrigeration for 24hrs + ! Great balks said no, they don’t have to refund on perishable products. Absolute awful attitude & really my own made bases taste far better, only buy these for convenience.
Try East pizzas, far better! And better customer experience altogether!

Dear Phil

Hi,

We are sorry to hear that your experience didn’t meet expectations and that the timing of your delivery caused so much frustration.

To clarify the timeline, while we unfortunately missed your requested delivery date, your order was not left sitting in a warehouse for days. It was dispatched on an overnight service for delivery the very next day. Because it has only been in transit for less than 24 hours rather than multiple days, the fresh dough, meat, and cheese are perfectly safe and suitable to be used.

We understand you reached out to request a refund after receiving our dispatch notices, but at that point, the parcel was already live within the DPD network. Once a fresh shipment is in the courier's system, we are unable to recall or cancel it mid-transit.

We take transit times for our perishable goods incredibly seriously to ensure everything arrives in top condition, and we are confident your items are ready for the oven. We appreciate your feedback regarding the communication and will use it to improve how we manage nominated delivery dates going forward.

What is a shame is we can see you placed 4 orders with us, so we can't be doing that badly to have earned that sort of loyalty.

A copy of your tracking status as of now:

02 Jun 2026 15:37 DPD We have your parcel and it's on its way to you
02 Jun 2026 07:46 We've received your order details, and we're expecting your parcel shortly

Kind regards,

Really disappointed

Really disappointed. I checked about next day delivery before ordering & was assured if it was before noon on Friday I would get it on Saturday. Nothing arrived & no notification. Aimee advised it’s 48 hours which in her own email to me is contradictory. After which Aimee was meant to be putting it to a supervisor but I’ve heard nothing. Not a great first impression & no contact received.

Hi Cerik,

We’re very sorry to hear about your experience and the frustration around your delivery. A first impression like this is far from the standard we set for ourselves, and we want to get to the bottom of it.

We have searched our system for an order or support ticket under "Cerik" but haven't been able to locate your details. If you could reply here with your order number, or get in touch with our team directly, we will look into this immediately to investigate exactly what happened with your order and the communication you received.

To clear up how our shipping works: at checkout, the options are based on what's in your box. If an order contains only non-perishable items, it defaults to a Tracked 48 service to keep costs down for you, though faster options are available. However, if your order contains perishable products and was placed before noon on Friday, it absolutely should have been dispatched that day on an overnight DPD service.

If we have missed the mark here, we want to make it right. Please do send over your order number so we can sort this out for you straight away.

Best regards,

Team GBOF

Disappointing first order

Disappointing first order. I ordered the starter box and some extras. It was missing the dust bundle I ordered, one of the jars of sauce, the salami and the fresh cheese. The family has been so excited to get our new pizza oven going and this has somewhat ruined our plan. I am hoping the quality of what has arrived will be good, but the service is not great. The website problem reporting is also terrible. And no customer service phone number. I hope to leave a better review once they have responded to my e-mail about all this. I read great things about this dough.

Hi,

We are incredibly sorry to hear this. Having this many items missing from a box is highly unusual for us, and we are gutted that this has put a dampener on your first pizza night. We know how much excitement goes into getting a new oven fired up, and we've completely missed the mark here.

Because we are a small team, our email replies aren't always instantaneous, but please rest assured that we work through every single message in order of receipt, and we will be on this. If we haven't already reached you by email, someone will be in touch shortly to arrange for the missing items to be sent to you via overnight delivery.

We really appreciate your patience as we sort this out, and we genuinely hope the dough lives up to expectations once you get to stretch it. We won't leave you hanging.

Next day delivery for a premium fee is a myth.
Only after the order is placed they would claim delays but won't notify you about this or give you the option during payment that delivery times might be longer. You have to reach out and then all they do is point you to the disclaimer fine print.

Hello

We are sorry to hear you were disappointed with the delivery timeline and felt let down by the communication.

To clarify how our shipping works, the premium next-day fee only applies to our specific AM delivery services. The fee you are referring to is our standard shipping cost for orders that fall below our £40 free delivery threshold. While we provide an indicative delivery slot at checkout and always endeavour to hit that schedule, it is unfortunately not a guaranteed timeframe.

We try to be as transparent as possible when we are up against it, which is why we highlight any temporary backlogs immediately within your order confirmation email. If a customer sees that notification and isn't happy to wait, they are always welcome to cancel the order for a full refund before it leaves us.

We always strive to offer a fast, efficient service, but during peak operational periods—and over the recent Bank Holiday weekend—delays can occur as we choose to give our small team well-deserved time off to enjoy their weekends.

If there is anything else the team can do to help clarify your order details, please feel free to reach out to us directly.

Kind regards,

Hi Andy

We are sorry to hear that the timeline for your delivery was so frustrating, especially when you were looking forward to trying the product.

To clarify what happened on our end, your initial order was unfortunately damaged in transit by DPD. While we don't own DPD and courier handling is ultimately out of our direct control, we completely appreciate that it's your experience that suffers when they drop the ball.

The moment you reported the damage to our support team, we issued and dispatched a full replacement order to make it right. Because we had to restart the process due to the transit issue, it sadly pushed the total time for your original order.

We always take full responsibility for ensuring your items arrive in perfect condition, and we're glad the replacement arrived safely. If there is anything else the team can do to help, please don't hesitate to reach out.

Kind regards,

We are sorry to hear that you were disappointed with your experience.

Regarding the delivery, we did include a note about a short delay in our order confirmation email to ensure all customers were updated on timelines, but we appreciate it’s always frustrating when things don’t arrive exactly when expected.
