I have been selling for a while on eBay and have only recently been having issues with multiple non-paying bidders and spammers and such. Fine, I 'll deal with that, but what I can't deal with is a recent buyer who was sent an authentic, NWT Gucci bag in perfect, store-bought condition who now claims that there was a pen mark on the bag and she wants a partial refund. This is after she haggled with me and convinced me that she would buy the bag only if I sent it for free with the original Neiman's receipt. I did that. Now she says that she wants to keep the bag but she wants a partial refund because the bag has been used by me. What the ***K? I told her that I don't sell used bags and that I had inspected the item prior to listing it and it was perfect. How should I handle this? I told her to send me a picture of this pen mark that she complains about. Thanks.
