If you have bought this on Ebay, and it isn't what the seller said it was...you can get your money back.
Contact the seller, explain what is wrong with the item purchased. This gives them a chance to resolve the issue amicably...if this cannot be done, then contact Customer support and open a case.
If E-bay connot resolve the issue with the seller you may get a refund on the price.
If you paid with Paypal there is buyer protection.

I know it is a hassle to do this, but if you don't do it then others may also fall into this trap.
It maybe that the seller didn't know the flash drive was not as he/she purported it to be, and they can then take it up with their supplier.
