OK, here we go! My SIL sells on eBay and this one guy bought something from her and promised to pay withing a week even though the auction clearly stated "payment is due within three days of the auction end". So, a week goes by and she hears nothing. He has great feedback so she isn't worried at this point. Then another few days go by and still no payment or contact. She emails him and asks if he still wants the item because if he doesn't she was going to re-list it! A few more days go by and he emails her to tell her that he changed his mind and that if she won't leave him negative feedback, he won't leave her one either!!! WTF?! Sometimes she buys me my LE LVs on eBay and one time she purchased something because I told her to and then in the morning I really regreted my buy so I asked her to email the seller and offer to pay his/hers listing fees because I felt horrible for not going though with the sale. The seller was nice enough to accept the offer and was very nice about the whole thing. This guy had no F***ING remorse whatsoever!!! And to threaten someone with a negative feedback?! C'mon!!! I told her to leave him a negative but she refuses to do so! I would've let it go if the guy wasn't a jerk and didn't tell her that! But the fact that he did really bugs me! What's your take on the situation?
