For 6 months I have been trying to get refunds on gas and electricity accounts for a property that I sold at the end of January 2023. I had accidentally overpaid. I am heartily sick of spending hours on the phone to British Gas "support staff". Lie after lie, "cheque is in the post" over and over again. Staff who promise to sort it out but then just stop communicating. If you're reading this wondering whether to become a customer, please do yourself a favour and try someone else. Horrible company, worst I've ever had the misfortune to deal with. The only reason I don't give up is that I don't want them to profit from their own incompetence.
