<prompt> Human: Hi. I recently bought a 128gb sd card from a seller on eBay - I was careful to avoid the ones that say this is an upgraded card from 8gb so I was hopeful it was genuine. When it arrived I started transferring my music and lo-and-behold it corrupted after about 8gb. I tried reformatting and trying again just to make sure it wasnt just a glitch but that just killed the card completely. Obviously my first step was to contact the seller but there was no reply so I raised it with eBay. After a couple of weeks of them waiting for a response from the seller they stepped in to see if I was entitled to their buyer protection - I was pretty confident theyd find in my favour, I was clearly sold a fake item not as described. However, to my dismay, they came back saying because I had tried to transfer files the item couldnt be returned as sold so I wasnt entitled. I made the point that how was I supposed to know it was fake without trying it out?!? They went away and reconsidered for all of 24 hours and came back saying well you tried to format it, that counts as an attempt to repair so apparently they wont cover it. Now obviously with hindsight I shouldnt have told them I tried to reformat it but in my opinion that shouldnt matter - I was sold a fake item by a scammer - he obviously doesnt want it back because its worth pennies so I should be entitled to try whatever I can to get it working. Anyway, I can argue my case until Im blue in the face but I feel like eBay have made up their mind not to refund my money. My question is can anyone offer help as to what to try next? - some sort of consumer rights group I can contact. Maybe if I contact SanDisk themselves and bring it to their attention they might at least urge eBay to clamp down on these scammers.  <response>: Im not sure rpersonalfinance is really the right place to ask this sort of question, but Ill try to give you a few ideas you could chase down:Say that the item was not as described and may be counterfeit, and that you had no way of telling that until you attempting to use it it: The fact is that you had no way of knowing it was counterfeit until you had used it, so that you modified it is completely irrelevant in this case. Of course, it is a rewritable medium so you didnt permanently modify it anyway...Contact your local trading standards office, and if you paid via paypal then lodge a dispute with them.When you respond to ebay with the above, ensure you also mention youve contacted your local trading standards.
