Appalling service, keep away from British Gas I overpaid my August 2021 electricity bill by 236 units, then in December 2021 British Gas hugely overestimated by almost 2300 units the electricity meter reading and quickly took £519 from my bank account, while my electricity account was still in credit. immediately I stopped my direct debit payments. I sent 3 letters to their complaints dept in Rotherham with all the proofs, but British Gas do not care. They did not give me the 2 refunds I am entitled to. I am writing to the Energy Ombusdsman in Warrington and have also contacted the BBC Consumer Programme Rip off Britain. Change your energy supplier as soon as possible!
