Worst experience ever with an energy provider. I thought NPower was bad but British Gas is the pits!! I was with them for only four weeks but I was relieved to get back to Octopus!! British Gas did everything wrong. They tried to charge me for energy from 1Oth July, when the flat was not even ready for occupation and was not bought until 31st August. They would not believe me even after evidence from my solicitors and the builders. They threatened me with debt collectors when I owed nothing and tried to charge me £28 for the debt agency fees!! They created a fictional bill for £109.51 which they claimed was unpaid and then hounded me for payment despite providing all the evidence to show it was incorrect. Finally I involved the Ombudsman who immediately realised my problem and dealt with the matter, awarding me compensation, an apology and correct billing. British Gas appealed and wriggled out of the compensation and apologies, but promised a correct bill. Their "correct bill" is still not correct and they have now closed the case, as has the Ombudsman. However, the errors have not been corrected and I am shocked that the Ombudsman has allowed this. Disappointed in the Ombudsman and British Gas.
