Currently in a huge dispute with British Gas. They have cancelled and replaced my bills multitudes of times (seven times just in June?). Each time they replace the bill they prevent you from seeing the previous one so you can't see what changes have been made. I, however, have downloaded each bill and pulled up one from 4th July which showed from 4th Oct-4th July I was in debt by £437.62. I cancelled my DD after a phone call with a rep who said I had to increase my DD payment threefold and I had no choice!!? I am now making one of payments each month of what I can afford. After I took this action my bill was cancelled and replaced to show a new bill for exactly the SAME period now saying I owed £870.85!!?? I have looked closely at both bills and can see how this was achieved. They changed the first meter reading for both gas and electric on 4th October making it much lower (how can that change - they took the reading?) so that meant that my usage over the same period was so much more!! I have written a letter of complaint to BG and am waiting to question someone over this. I am very suspicious of what the hell is going on here!
