I've just been hit with a final value fee for an item I didn't sell because ebay thinks i did a deal offline. A man asked for my number to arrange collection. I provided it assuming he wanted to discuss the collection before he placed a bid as he said he would offer £300 for the item. He didn't even buy the item! This is a rookie error as I hadn't sold anything on eBay until this point. Help!! I really don't want to lose £30 for an innocent mistake.
