Worst company I've ever had to deal with. Firstly, they added a £800 charge to our account out of nowhere (after we've only been at the property for about a month or two!). After about half a year or longer of trying to resolve this issue with them (and being ignored for all this time) they tried to take legal action. It had to get to this for them to finally realise their mistake and take off the random charge they added to our account. Now, 3 months after leaving the property and closing our account (we emailed them to close the account on the date of our move out which they confirmed they will do) they have sent us an email asking us to pay for the bill for the property we left. Again, they refuse to accept when we say the account is closed and keep harassing us this time over email. We are now with OVO energy and are having no issues. Stay away from this thieving company!
