I have just had a look at this and have also received a letter just before Xmas saying that BCW acted for British Gas and I owed them £407.72 for electricity used at a house which I rented over 14 months ago. I rang BCW and asked for a break down as to how this amount was arrived at and they informed me that they could not speak with me ! but I could ring their client direct and get the information from them. I duly rang British Gas and they told me it was for a period of up to 5 years ago and for different houses which I had rented !! They have sent me a statement, but it is not a breakdown and only shows what amount is due. furthermore, and what was really worringly at the time, back in May British Gas took the money which they claim is owed to them, from a bank account without permission and after a prolonged conversation with them over two days I managed to get the money back. they took the money using an old direct debit mandate - which had been cancelled - which was in my opinion Illegal bearing in mind I have now been with Scottish Power for over 14th months and had cancelled all direct debits with British Gas over 14 months ago. furthermore, the British Gas account was in my sole name and they took the money from my partner's sole Bank account. In any event I got the money back and asked them in May of 2007 to let me have the breakdown of how the amount was arrived at. I heard nothing until I received the letter from BCW. Any advise of what to do - I am loathed to pay for something that I do not know how has been arrived at. It would be good to know the next route to take. thanks F.E.ALL
