i had a pre-payment meter with them and decided it was getting too expensive, i called them to take it out. I never received a bill for the next quarter-called them several times, kept being told someone would call me back but never did. I told them i wasnt getting bills and if they wanted to continue to give me free electricity that was fine. Eventually i managed to speak to someone who tried to help. They told me they would look into it and call me back. About a week later they did call to say they gave my meter to someone else, because the other customer had been paying it they thought it was me as it was still in my name! They eventually told me i would have to pay almost three hundred pound for my bill!!!!!!!!!!!
I told them i wasnt happy as it was their fault and was told they would give me a reduction. Several phone calls to them later cos i still didnt receive my bill- i was told i would have to pay the full amount. When i said i was told i would get a reduction they told me i was given wrong info. I said it was too close to xmas and couldnt afford that. They said they would accept £40 per month until it was paid and sent me a card to pay it at the post office. I was doing this until they sent me my next quarter bill, it was rediculous also and still owed the near same amount on my previous amount. They told me it was cos i used my washing machine too much! They have now recently put up my monthly payment to £70!!!!
I am trying to pay it off, then i will definately change suppliers - you should do the same!
