This is a review of their Electricity supply business. They do everything to keep more of your money than they need (was >£1000 in credit at one stage). Simply shocking customer service designed to avoid you getting anything changed. Patronising staff, which gets worse the higher up you go. Now they have changed their Energy account website, I can't even access the data I need. They won't even pay me back the Government rebate, rather they add it to my credit. They have hung up on me twice. I have used Live chat, telephone and they even gave me a specific e.mail to write to, from which I have never had a reply. Letter to Ombudsman being written now. As soon as I can, I will get out of the service that these money grabbing leaches provide.
