I was Scammed by a Buyer in Toronto last year...
I sold a photograph and a few weeks later I received a "item not as described" Claim saying the photograph was a restrike.
I accepted the return because I couldn't be bothered to argue with the buyer.
He sends the package back to me with a Tracking Number and Signature Confirmation
eBay sees the Buyer sent back to the package through the INAD claim and prompts me to refund the Buyer.
I open the package and there's two pieces of cardboard and a Sports section from the Toronto Sun dated on the day the package was mailed out.
So he read his Morning Paper with breakfast and headed down to the Post Office.
I send the Buyer a message about the contents and he tells me the photograph was returned.
He leaves me Negative Feedback saying, "Seller Doesn't Refund".
Thankfully the Feedback Specialist at eBay Customer Service sided with me on this case and the Negative was removed.
