Query: Counterfeit memory

I bought this memory from a vendor at Amazon. I had some issues with the memory from the beginning, but you know how it goes, I let time pass. After I finally got around contacting the vendor, they refuse to help me saying that the warranty with them had elapsed. So, I contacted Kingston. They were curious about the behavior of my memory and they asked me to sent it to them. I was counterfeit. Even the color of the stick did not match the color of their 2 GB!! (should be lime, it was purple). Kingston asked me for all the paperwork about this purchase, which I did. They in turn sent me a Real Kingston Data Traveler 2 GB USB Drive. I have not had any problems with the real flash drive.
