Hi, I pay my water bills to South West Water by direct debit. I have received an annual reveiw to my account which was about £10 a month more than I am currently paying. The company actually owe me over £70, (I had received another re-embursement about six months ago for a larger sum). I disputed the amount and was told that on doing the calculation manually my monthly ammount would in fact be reduced by £10 a month. I asked why this hadn't been done before the bill had been sent out and was told that it was a mistake by their computer. They assured me that I would be re-embursed and should receive a cheque.After a week had passed I called S.W water and asked where my cheque was. I was told that cheques were only done on Fridays, so as I rang on the previous Saturday I missed the cheque day. He explained that it had been done but was waiting to be signed, (there must be some little bloke, sitting in an office somewhere signing cheques all day, because a multi-billion pound company finds this the most efficient way to run their accounts. It is now into the third week and still no cheque (even when I receive it it will take 5 working days to clear, so they have had my money for nearly a month.(and everyone else's in the same situation as me). Is there any way of getting the interest on the re-embursement. They must be making an absolute fortune on their customers money.
