When you open a return request on ebay and the seller doesn't respond you can escalate the case to ebay within 30 days of opening,by going back in to the view case details,and ebay will refund you without the seller getting the item back,so the seller has ran you out time now.
Look to your payment provider for help now,so your card issuer if you paid for the item that way on ebay,or pay pal
