Used the wrong address for electricity at the beginning of the contract , took months to put right, didn’t seem to use my actual meter readings for electricity or keep track of payments , now at the end of the contract they sent me a bill overcharging me for electricity , it was amended after disputing it but no explanation why this happened, and using a date that was before they took over from old supplier.the final payment still excessive and clearly wrong give me 7 days, won’t let me access info on online account and who has hours to spend on the phone keep going over the same thing , no confidence that they are using the right information and what they are charging is correct. I will never use British Gas again they don’t care and overcharge as if their right. The CEO should look at the comments on this site and hang their head in shame.
