Query: Unfortunate

I purchased the Nintendo DS Lite Crimson/Black for my son. It was a second-hand game. Unfortunately when it arrived, it did not work properly. The game has two screens, both of which are necessary to use the game. One screen was blank with half the screen grey and half white. The other screen was not clear with a very "fuzzy" image.On the plus side when we contacted Amazon for a return, there was no problem. We were sent a return authorization and label electronically and promptly mailed the defective machine back. The cost was promptly refunded.
