I recently sold a FLAWLESS Dual-Tray DVD player on ebay. I shipped USPS Priority with insurance and delivery notification at my expense in a Dishnetwork receiver box with all the packing. The buyer receives it and says it's broke; it keeps switching back and forth from tray to tray and will not accept any DVD. The buyer then takes it in to Best Buy and their "Tech" verifies that indeed it will not accept a DVD. So the buyer ships it back. But when I look at the player, it is obvious that it has been opened and now has scratches where someone pried on it to get it open. It shows other screwdriver marks along the bottom like someone didn't know how to take off the hood and also has a small dent in the hood. Upon questioning the buyer about the scratches, he admits that the "Tech" at BB opened it but knows nothing about any scratches. What would you do?
