It is just over a year since my 2 months of hell dealing with this company. It started by my enquiring by phone for an E10 supply. Yes I was told,no problem. They took my details including my email address. I specifically asked them to make sure my surname was spelled correctly as it is unusual. 10 days later I had heard. Nothing, called them and all was fine they said, even though I hadn't had terms of contract. I queried this and then was told we don't do E10 so your are on E7. I didn't want this change so said I don't want to move onto OVO. You'll go straight back to your old supplier was the reply. 2 days later I can see from my in home display I'm now on OVO E7. Several calls later and still no contract I'm asked my home address, I give it and then am queried about my other address and account. It appeared I now had 2 addresses and supply numbers set up. I download the app set it up and yes my address and another the other side of the country. I found because of the errors they had made I had access to another customers account because they misspelled my surname in my email address to a more common spelling. Two months later, too many phone calls to mention and finally I contacted my MP. Even then things weren't right. Email arrived from OVO we've closed your account and deleted your email address on our system. Same day a new email, please set up your password on your account. Well to say that I was at my wit's end wouldn't be anywhere near how I felt. I even had 5 hours on the phone one day. Finally someone in the resolution team who knew their job fixed the issues. They could see another account someone had changed all the customers details to mine because of the misspelt email. This had been done so efficiently OVO were going to write to them asking for all their contact info. I eventually was transferred back to my old supplier but my meter(installed that year) would have to be replaced again as it was charging the wrong rates for part of the day. No apologies from OVO, no money apart from statuary £30 for erroneous transfer.
