We moved house and British Gas assured us all was fine, it wasn't. They told us repeatedly that the account was set up for our new address but then a different address appeared on our account. They tried to charge us almost £800 for a month's gas for an address we didn't live at. After a LOT of phone calls and money taken from our bank account they admitted it was their fault and we didn't even have an account with them... unbelievable... We were with SSE [who sorted everything out in under 10 minutes over the phone] British gas offered to return the money they had taken and pay us compensation for their mistakes... £9.51.... Embarrassing.. Never again, avoid at all costs.
