Sorry you are having so much trouble! It seems these days that ebay is largely populated by ignorant gits and scammers. A good few years ago I used to sell a lot of high-end watches (Severe flipperitis) on eBay and all I dealt with were decent guys and I never had a problem. I stopped selling on eBay years ago when I sensed things were changing and now I would not bother selling a carrot on there!
