Sold me a fake product worse website. Review on Ebay

Ebay.in is the worst online store in india they dosnt check any product if it fake or real I bought a 128 gb pendrive from this website deal is good it cost me only 200 bucks so I thought chlo buy it after seven day they delieverd a fake product when I plug it in my laptop all looks good it shows 128 gb space but when I tried to copy paste some file in it that also easily done But when I tried to play that stuff which I copied in that pendrive shows error every time .when I removed and plug it again I sw that there is nothing in the pendrive free data space is again 128 gb.i do this copy paste thing twice but the result is same then I realised its a fake pendrive.I called the customer care of ebay.in they said that the replacement and gurantee are solely provided by the seller not by us contact your seller.and the seller dint reply my email.Actually the problem is anyone can become a seller at ebay there is no quality check and no varification .So guyzzz dont ever buy anything from this website pathetic service
