Horrendous experience. After 7 months of having duel fuel from them I got an email saying "sorry your leaving us" etc. I called to find out what was happening and was assured it wouldn't happen again. I happened again and again. I lodge a complaint and after investigation was told they have never supplied my gas and were accidentally supplying another home and were closing my gas account and unable to tell me who may be my supplier. Email basically saying there's nothing we can do, we won't respond to further contact. I have now also has a letter saying that my electric supply has swapped to NPOWER by mistake and they are swapping my back to my non-existent other supplier. I'm worried my services are going to stop and the phone line has a message saying it is not taking calls. I'm now switching and see if they have the gall to fine me for ending the contract early. Fingers crossed I can do it before they completely balls up my supply!
