When I joined they took two months upfront, after six months they increased my electricity charge because it was going to be a severe winter????? I could have understood if they had increased gas charge, When I challenged it I might as well have been talking to a rocking horse. At end of contract they could not offer anything on fixed rate and it meant a £200 increase per annum so I gave notice and left. Now I am over £100 in credit and have told them it is budgeted for and will cause hardship If I have to wait the 8 weeks they say it might take. They are not prepared to take individual circumstances into account. We are pensioners and my wife is disabled and they know this. I am not the happiest bunny in the warren.
