If your ok with the £50 I would ensure you have the balance spread over a long time. I would personally say no I won't accept £50 I think you could ask to meet them half way and to repay the balance over a shorter period of time if you are in a position to do this.

Hi Panhandj I work for gas and electricity supplier. Not the one in question but another of the major ones. I don't know what N Powers procedure is for the 4/5 dial mix up but have come across this in the company I work for. You need to follow complaints procedure with N Power. If then the dispute is not resolved to your satisfaction you then contact the regulator. Normally the regulator wont assist unless you hsve followed the company's internal complaints procedure. 1st step which you have already done is to contact customer services and register your complaint. 2nd step. If the complaint has not been resolved you ask for it to be referred to executive complaints team and request they contact you by phone or letter. 3rd step. If this has not resolved matters the exec team will refer the complaint to head of customer relations for review. 4th step. You will receive a final response letter which will explain their final position. If you receive your final response letter or they haven't been able to resolve your complaint within 8 weeks you have the right to go to the regulator. The energy companies also have something caked "The billing code" you need to be asking if your case falls within the billing code. If you do end up having to pay then you can ask to repay the amount over the amount of time you have been billed incorrectly. Hope this helps.
