Re: Back-billing complaint
I am writing about a problem with how my account has been billed. This problem falls under Ofgem's back-billing rules.
The Ofgem back-billing rules say I should only have to pay for 1 year’s energy use if I haven’t received an accurate bill for over a year. Please make sure that the Ofgem back-billing rules are applied to the balance on the account.
Please respond to my complaint in writing within 10 working days. If you fail to respond in this time, I will consider taking the matter further.
