British Gas are a bunch of robbing sharks. I switched the agreement when we moved house and when the policy ended they magic up a figure of supposedly unpaid usage from over the winter (6 months prior). as time had gone by you can neither prove or contest it. And rather get threatened with debt collectors. So we didn't have a bill in December i paid £50 upfront so the agreement of the outstanding balance ends in November. Well December rolls round, i get verbal confirmation from British gas saying there is nothing owing on the account and i am cancel the direct debit. Upon doing this i then get another threatening letter saying i still owe them another payment!!!!. In british gas's infinite wisedom there complaints procedure consists of getting repeated texts and emails saying pay now or we'll take you to court!!! Once again, an energy supplier really proves they are for themselves and not the customer. C*U*N*T*S!! I will never use again or recommend British again
