I've always paid my bill on time without issues. They told me they were struggling to connect to my smart meter and have had issues non stop since. I have continued to pay my usual amount as I was ensured my bill would be revised and amended so thought better to pay what I usually do than not. They've since removed all my bills from the last 4 months on my account and given me a new one stating I've used over £700 in just electric for this period. Stating this is the accurate usage charges. I still have emails stating my previous bills were ready followed by emails that they were paid. The customer service agents have been rude and extremely unhelpful, I told them I would approach the ombudsman and they had no care what so ever. They even told me maybe I should seek professional help if I am that stressed about the bill. They are an awful company and you should completely avoid them at all costs. Prices are going down and they're trying to rob us blind to keep their profits up.
