To whom it may concern,
Re: Complaint against British Power
I have still not received my first bill at this address, despite contacting you several times to ask for one. I moved into my new home on 10 July. I requested a bill on 3 August, 10 September and 7 October.
Please send me a bill as soon as possible.
I first complained on 22 October 2022. I understand you have 8 weeks to resolve my complaint before I can go to the energy ombudsman. If we haven't agreed a resolution about my complaint before the 8 weeks have lapsed, I understand you'll issue me with a deadlock or 8 week letter which means I can then take my complaint to the energy ombudsman.
I have calculated that the 8 weeks will have lapsed on 17 December 2022.
I first contacted you about this by email.
Please respond to my concerns, including any other information you feel would help resolve this complaint.
Please reply in writing within 10 working days. If you fail to respond in this time, I will consider taking the matter further.
