British Has took over my gas and electric when The Peoples Energy went bankrupt. At this time my bill went from £160pm to £260pm, I was fine with this as everyone's bills had gone up. One day, around June/July last year I got a letter saying that my bills are going up to over £1000pm! This was obviously some kind of mistake as I am just a three bedroom family home with standard appliances. I began online discussions with British Gas, this went on for hours, the lady seemed very helpful and we discovered that I actually had another dormant account that was £1300 in credit, I was told this was going to be offset against my active account, I then had to produce 7 days meter reading to get to the bottom of the issue, maybe a faulty meter. I left the discussion feeling satisfied that the issue was getting dealt with and went about providing the requested information. NOTHING HAPPEND FOR WEEKS! Again I went on the online chat for hours. I had to start the whole process again. Again I was talking to a helpful chap called Nathan, then we began to chat over email, and again I provided 7 days of readings with images. However, I checked my accounts again and the £1300 credit in my dormant account had vanished and had not been applied to my active account. Nathan said there is no record of it ever being there, but i had proof as it was writren and agreed in the previous transcripts on the online chat. Nathan assured me that from now on I will only be dealing with him and promised he would get this issue sorted, he thinks The People's Energy have provided the wrong end meter reading when transferring my services over, he will be in touch within 2 weeks and the matter will be resolved. AGAIN NOTHING FOR WEEKS. I then get an email from someone completely different, Nathan has left the business, I will be taking over now, give me a few weeks and I'll be in touch. AGAIN NOTHING FOR 6 WEEKS. So I emailed back, urging them to please get the matter resolved, it has caused a great deal of stress and sleepless nights for myself and my wife, we know debt is building up, but noone is getting back to us! NOTHING FOR ANOTHER MONTH. Then without any correspondence whatsoever from British Gas I get a letter from a debt collection agency saying I owe £5K, I know what my meter readings are and I know it weeks take nearly 2 years for me to use that much energy. In short they have stolen credit from another account of mine, ignored all correspondence I have given them over hours and hours of conversation and emails and they have the worst customer service I have ever experienced, British Gas are ruining our lives!
