Have you appealed the case? After refunding you can appeal it, arm yourself with all your evidence and call eBay CS.
To contact eBay Customer Support type in Advanced Search in the Help & Contact tab top of your eBay page , and scroll down to bottom of that page, there should be two options for contact, Chat with Us, and Have Us Call you. Both will give an approximate waiting time too.
Lines are open now until 10 pm tonight.
