Appalling customer service. Trying to change from British Gas, due to a previous complaint, electric side done no problem, but the gas side well that's a different matter. They claim I owe them money. I don't as it is from the previous tenant 5 years ago, which to my knowledge was sorted out 5 years ago as they refunded me the money taken off for the debt. I have been on the online chat on 4 separate occasions just to be told to call a number, you call that number and are told to call another number, and then was cut off. I also requested the transcripts from my online chats and they were never received. So now I am going to the ombudsmen.
