I am facing a problem of this kind right now. I shipped the item back to the seller and confirmed that the seller has now received the item. THis is because the item was not as described in the listing. However, ebay has not done anything with regard to my refund except for a few mails telling me to wait. Now I'm starting to question the legitimate credibility of e-bay.
I shipped an item back and e-bay has not given me my money back
