I had this studio flat for years and had tenant in, it is empty for the past 18 months with no usage of gas or electricity today I had a bill for £2,389.10 for I do not know what? first they said it is for electricity and gas and when they found out my gas is a key card gas they said ok it is only for electricity, they do not tell me who signed any contract with them as defiantly it was not me or my agent, as I defiantly changed it to key one. I am not even sure they know where is my flat as if one owes them so much why they do not cut their product? they are the biggest scam. lets go to the court with them.
