I bought an item on ebay uk several months ago. I am in Spain. The item never arrived, tracking, royal mail signed for. Tracking is pathetic and showng nothing since june. I opened a case, only to be told i am not covered under the eBay guarantee. Now eBay have closed the case  due to inactivity for 21 days. I was away for 10 fays, and had no internet where i was staying, so could not tespond to seller asking if i had recieved item yet. I have tried to appeal ebay closing the case, but they won't let me appeal
