I feel very badly for the OP, and the situation in which you find yourself.
I do want to say one thing, as a person who has done much more buying than selling in general - there are as many bad sellers as there are bad buyers. I don't know HOW many items I have bought that have claimed to be in great condition, minimally used, etc. and then the hardware is scratched and flaking and the leather is scuffed and worn and the bag is DIRTY and I would NEVER in my life list the bag myself as being in "great condition" in those instances. When I get frustrated and message the seller, the usual response is that I am buying a "preowned" item, and my expectations were too high! I have owned many things that I was very careful with or used very little... if the item is truly in great condition, then that is the only time it should be listed that way! When I do list items myself, I am careful to both describe and take pictures of any and every issue I see with the item. I bought a handbag recently that was NWT, and the seller did not mention that there were big streaks in the finish of the bag. They said that they bought the item NWT in that condition,and that I should use an "eraser" to remove the discolorations!!
So, I just want to mention, that it's not whether the person is a seller or buyer, but whether the person themselves are honest or not. There are nasty people in both camps - and in my opinion, I have needed those buyer protection policies to help in these really frustrating circumstances. I have also been on the other side, talking with ebay for over 10 hours to get rid of a negative feedback left after the buyer didn't pay for an item and left an acimonious statement about my selling "fakes." So I understand that frustration as well, and just want to remind people tnat
it's not about "buyers" and "sellers" but about just being honest and decent people, which seems to be more of an issue than one would hope for. I have to admit that I sincerely hope that certain buyers and sellers on ebay get smitten with a hefty dose of karma!!
