Promised a discount to prevent me leaving Y,. Energy and held me captive by saying that they would call back. The discount was never applied, I spoke to 26 ppl,and they regularly left me hanging on the line and cut me off too. The worst customer service in the UK. Horrendously expensive. Nothing good to say about them. When I lodged a complaint they scratched it off saying they wanted it closed as they thought they had done enough. Many, many, many companies are much less expensive and head and shoulders over B. Gas to deal with. Even if you leave you will probably be quids in ....their charges are exorbitant, their staff couldn't care less, case handlers pretend to sort and then ditch, as they are likely to feel so miserable, dejected and sorry that they ever took a job from these useless Charlatans. Be warned they are failing rapidly as they do not employ staff to sort problems....they just avoid the problems by not answering the phone and not getting back to you. Tip=LEAVE
