PNY - Shoddy products, Doesn't honor warranty, HORRIBLE customer service

I purchased 8 PNY Memory kits to add memory to 8 desktop computers. One of the chips turned out to be defective. I contacted PNY for a replacement under their lifetime warranty. I sent them the defective part, at MY expense, and it was returned to me without them honoring the warranty. They now expect me to ship it back to them, again at my expense, with the other working chip, which I do not have access to. Rather than replace THEIR defective chip with a working one, this pathetic company chooses to play games and further piss off their customer
