eBay — Very poor customer service

I had ordered nearly a month ago sandisk 16 GB pen drive but still I have neither received PD nor the refund money and when I put cal to the customer care itz alwayz BG I think I have called 50 times but no response. So I think worst customer service of ebay .so in future I would never prefer to purchase anything from eBay n I request guyz not to purchase anything too.they have no interest on customers just they need money first and after that give dam to customers.
