A French energy supplier wants an extra 5,000 euros from me for my gas after me paying 46 euros a month standing order. They say it goes back 2 years but its still a ridiculous amount. I lived on my own, was not there permanently so the heating was used less than 5 months per year. They kept me on the phone from the UK for over an hour and a half and said they would not put anything in writing before I agreed to pay the 5,000 euros. Anyone know what I can do about this. I will pay what ever I owe them but it cannot be this much, they also lied saying the 46 euros a month was for the electricity which again is ridiculous, thanks
