Thanks @vyolla. Very disappointing that the Chat facility is no longer available - I was able to access it once in the last 2 weeks, but nothing since Friday. It used to be a quick solution for queries. The current Call Back wait time is 13mins.
The issue - a buyer has returned a new item, but has washed it. It was mint, but is now unsellable. He argues that that it has not been washed or worn, but the listing photos prove otherwise.
eBay seems to think this is OK, but I would like to discuss the matter further and provide evidence.
The fact that you can no longer leave negative feedback against a buyer who abuses the system or never makes payment is a complete joke. Buyer Protection - what happened to Seller Protection?
