Query: dissapoint

Although I received this stuff, this is non brand, not working for my digital camera (panasonic). I sent e-mails at several times for seller. I returned to this stuff for transcend company after I got RMA request from the company, I'm now try to exchsnge the stuff. I do not know whether my request is acceped or not. Because, basically, this stuff is "fake", not made by transcend. Please do not buy this stuff from chukwuking16 or Okoro Books as the buyer. The stuff will be send from Hong Kong.
