AMD motherboards

I have bought two AMD motherboards(with processor) for a small amount of money from a major department store. the first board I bought the processor was burnt. Mind you I had bought new. I had the board tested at the Store. They would not refund the money or take the board back because the processor was bad. They did give store credit for the bad processor though. So I proceeded to buy a second one. I still have both sitting in their boxes.
Has anyone else experienced bad AMD motherboards or was it just me?
