I've had nothing but trouble trying to close my account with OVO and settle the final bill, and my situation is still ongoing. Despite calling in on the day I left the property in question with final meter readings when the final bill arrived 6 weeks later they had failed to use the reading supplied and massively overcharged me. When calling in to resolve I was told it was going to take a further 6 weeks to generate a new bill. At that point I asked for my call to be escalated, but the manager at the "Apollo" team was unhelpful could do nothing other than start a complaint for me. Of course I've heard nothing from the complaints department, no emails, no phone calls so I have no clue what has happened there. A further phone call the next week where I finally speak to someone who is able to comprehend my frustration ends up with me being redirected to the "Apollo" team again. They promise to follow up with the complaints department, re-record my meter readings yet again, and promise the billing department is going to be able to resolve in 3 working days. In the mean time none of my emails have been responded to other than by an automated response. Three workings days later and I have a letter through the door, half of the final bill, which while it does finally mention one of my actual meter readings continues to estimate beyond when I left the property! I call in to OVO again and the most helpful part of the experience is being recognised that I have a complaint by the robot and discussing my complaint is moved to key 1. The representative I speak to now tells me it's going to be 3 to 4 weeks before my final bill is sorted, and they still have no idea why my complaint hasn't been addressed and no-one has contacted. Now it's 24-48 hours before a manager might get in contact when I ask for it to be escalated - but going on OVO's current track record I imagine I will be calling again later this week for another round of ineffective attempts as resolving the situation. I just want to pay my final bill and draw a line under the situation without being overcharged hundreds of pounds. To add insult to injury, they are holding the account at the property hostage and not allowing the owner to take control of an energy account, or allow another company to set one up until I pay my final bill, leaving two customers in the lurch for the price of one. If I could have sorted this all out online I would, but I also happen to be one of the OVO accounts stuck in limbo and unable to access any online services. Absolutely abysmal customer service and I will be recommending all to avoid OVO.
