BG are an absolute disgrace. After transferring from People's Energy (not by choice) they have got my first bill wrong 9 timed. Every time I managed to sort it they would then retract the bill a fee weeks later and issue another bill with no notification. It was only through constant checking that I kept noticing that they had changed it and had to spend hours on the phone each time for them to sort. Finally, managed to sort in August and was promised it wouldn't change which thankfully it didn't. However, I then received a new bill in January and I was over £250 in credit as I was overpaying (which I told them over and over again I was). I decided to leave this in my account and the app said that I could reduced my direct debit slightly which I decided to do. The next day, I check my account again (because I have zero trust in them) and sure enough, they've take another £154 with no explanation (just taken from my account credit) and the app now says I'm not paying enough. I've totally had enough of them. They just feel that they can take whatever money they want with no explanation or contact. Worst company ever - I would never recommend them to anyone. As soon as I get the money back that they have stolen, we will be moving to somewhere else.
