Symbio claimed I owed them £19 for electricity in October (that is 3 days - 1st to 3rd). I use 11 units a day which works out at £45 for October. By Symbio's estimate, I would have used £196 of electric in October. Fraudulent accounting as usual. Fortunately I had cancelled my DD. Now waiting for the administrator to claim I owe Symbio money. If that is the case, I'll be reporting them to the police and will be happy to see them in court.
