A purchase I made and paid for was not even sent out of the sellers store. When I realised that the items had not arrived I wrote to the seller asking for my money back. The seller did not reply. I wrote again giving more detail. Seller still did not reply. There was not a "ask ebay to step in" for me to take it further so I waited only to find that ebay closed the request.

How can I get this case opened again?
