Ovo recently contacted me (after 2 years of not being with them) to tell me I owed over £3K because they got both my moving in dates wrong and my moving out dates wrong. They thought I was still with them. I'd cancelled my account and paid the final bills 2 years ago, and called to check this was all good and they said it was, and even refunded me £44 at the end of my time with them. So, they amend the £3K, but I'm still totally confused why suddenly they're saying there is roughly £350 still left to pay. I get contacted again and see the dates and some other information in this mysterious "final bill" still appear incorrect. So I call multiple times, email multiple times (with no success, as I get told the email isn't registered to an account at Ovo, which just contradicts everything even more), and when I am lucky enough to get a response or through to them, I get told different information by different people. Two seperare people told me there is an error with this bill and to ignore it, while two other people tell me there isn't an error, yet still apologise that Ovo messed up my account closing procedure? Anyways, after a few weeks of being essentially harassed with emails and texts telling me I have to pay this dodgy bill, I had a long chat with someone at Ovo who yet again said there was nothing I could do. So in the already horrid cost of living crisis, they took a ridiculous amount of money from me and had no empathy or accountability. No one bothered to investigate it or understand it, they just got very sturn with me. I cannot stress enough how incompetent and disappointing Ovo's treatment of this situation has been, and how little they seem to care if you're a past customer as opposed to a current one apparently. Avoid if you can, maybe you'll have a better experience, but I've never dealt with this level of gross unprofessionalism and, essentially, bullying. I can see from other reviews, this is a common mistreatment and issue with other customers already. How many different kinds of disgusting do you have to be to ignore it over and over again? Nasty of piece of work you guys are. Kicking customers when down. Hope you get your all your desired moneys
