You're not the first to meet this problem. It's just that someone in OVO hasn't yet progressed your https://[url=http://ovoener.gy/myovo*My OVO[/url] page to the next stage of being made "live".
Simply send an email to firstname.lastname@example.org with the meter readings and Customer Services will have to update their database manually. The email method gives you a date/time stamp as proof of when you submitted the required information.
Don't forget to provide them enough details to identify you with. If you know your account number, then give it, and in any case state your post-code. You should receive an email acknowledgement.
There is absolutely no possibility of you being cut off from your energy supplies. Ofgem would come down like a ton of bricks on any Energy Supplier which did that!
You actually have a 14-day "cooling off period" at the start of a new Energy Contract, because that's a requirement of the Consumer Credit Act. And that's one reason why OVO don't make your https://[url=http://ovoener.gy/myovo*My OVO[/url] page fully functional at the outset. Different features get enabled as the switching process takes effect.
