I am a seller.I needed to cancel a winning bid. The buyer denied the cancellation but did not pay.

What to do?

The only two reasons that are Defect-Free for a cancellation are "Buyer Request" or "Problem with Address".

Any other, particularly Out Of Stock, gets the seller a defect.

Have you set your Seller Preferences to Block some unwanted bidders?
