I take it that you have opened a return request, through the resolution centre? Or did you open a money back guarantee case? Or did you ask the seller to send you a cancelaltion request?
It's complicated to advise you without knowing what procedure you have followed. Whatever it is, just continue with it in the usual way. All refunds are made through eBay's resolution centre. If a seller can't or won't refund you, eBay will. Where a seller's funds have been held, they are available to refund you - which is why they were held in the first place!
A cancellation request or money back guarantee case should produce your refund almost automatically, provided you follow the process. A return request is less clear cut; unless this seller's returns policy to accept returns, they can refuse it. If they do accept returns, but refuse to do so, the request can be converted into a money back guarantee case.
