This is without doubt the worst company I have ever dealt with. These sharks over charged me by £3k & made me wait over 25 weeks for them to pay back what was rightly mine. I dealt with over seven customer care operators (all of them were useless) & super unhelpful. All told a pack of lies & made up some rubbish about them not having the correct metre on records. After going to the Energy Ombudsman's to help me with this, they were the only ones who really helped me. They were superb from start to finish. This company turns over £5 billion a year & they are all told not pay back their clients money which is owed to them. I’ll be leaving these sharks as the thought of these imbeciles taking anymore of my money makes me feel sick. DO NOT USE THIS COMPANY FOR YOUR ENERGY SUPPLIERS.
