Following Ovo’s inability to resolve my billing issues moved to Octopus - who so far have been very good. OVO said they would pay the money I was in credit at the closure of my account within 10 days of the next billing period. It is now over two months and endless emails and calls. People at OVO are pleasant but ineffective. Even wrote to Stephen Fitzpatrick the CEO only to be referred to their complaints procedure which stated they would respond to me in 8 weeks which they had already exceeded! OVO are the worst company I have ever dealt which is saying something as I used to be an O2 customer.
