Hi, Can anyone offer any advise on how to deal with N-Power? I was with them for 2 and half years, and they kept messing up the DD and they sent so many wrong statements and bills. Eventually we were set up on a plan which expired in April this year. They then sent us an invoice saying we owe them £3400 as we have been paying the wrong amount even though they put us on the tariff and set the DD up. I've complained and complained and complained to them. I eventually managed to switch providers as they blocked it at first. It has now reached deadlock with their final say on the matter is they will knock £250 off due to the bad service but because we are no longer a customer of theirs we need to repay the rest within 2 years at £132pm. At the moment our outgoings are a lot more than our incomings so their is no way we can afford anywhere close to this. We offered £20pm but they wouldn't accept that and are now threatening to get a 3rd party debt collection involved, even though I have never signed anything to say they have authorisation to pass my personal details to another party. Their customer service is absolutely appalling. I am going to go to OFGEM but will it do any good? I am just worried now that we are going to end up with bailiffs banging on the door or extra charges being added. Can they really force us to pay £3100 even though it was them who set the payment up incorrectly? Please help, we are at the end of our tether.
