British gas are absolutly terrible. I have been overcharged for a long time. I do not use over £4000 worth of electricity in one day!!!! or £400 worth every month for six months. I have been trying for nearly a year now and they will not sort it out. It must be the very worst company in the world. I am only using electric as there is no gas supply and live alone. I use very little electric. My meter is faulty which they have admitted but will not correct it. Two engineers have been to look at it but will do nothing. When I call BG about it they say they will call back but never do. They are a total RIPOFF!!
