I switch accounts regularly, not just energy but insurance, telecoms, banks,building society's you name it as I know in business today there is absolutely no sense of loyalty to customers whatsoever.
So to be brief I switched to save £20 per month from OVO to EON in October 2016 (yes 6 months ago!!!) and yes you guessed it. OVO have still not sorted it or refunded me a penny yet and it transpired would not have done if I hadn't contacted them!, and I had stiill been paying a higher unit cost with OVO as they didn't switch my gas supply to EON
Basically now I sent a recorded letter (the only way it appears to prompt a response), anyhow a nice reply came from Heinie on 21st April which I responded to promptly ------- THATS IT, JOB STOPPED. I HAVE SENT 5 MORE COMPLAINTS ON EMAIL TO NO AVAIL..... I AM GOING TO BILL THEM £70/ hr UUUUUUUUGHHHHH ,,,

Yes this needs sorting one way or another. As you've switched supplier, a common cause of a delay in your final bill and refund is us waiting on some info needed to close your account, like the final meter readings. This sounds different though.
I've moved this topic to the Pay monthly forum, and changed the title. That way, other users who have had an issue since switching supplier can get the advice they need.
Hope this helps,
