I am so pi$$ed. I sold a bag yesterday. the winning bidder sends me a message that she had mistakenly input the wrong amount and that I should offer the bag to the next highest bidder. She said that she didn't want to spend more than $400 for the bag, but her final bid was $510.01. She even mentions that there is another bag just like mine for about $80 cheaper and that one is also too expensive for her. I happen to be watching that other bag because i like to compare my auction results with others. It turns out that two hours after my winning bidder won my auction, she hit BIN for the cheaper bag. And I believe she paid right away because the other seller just left her positive feedback. I am so angry. The bidder totally lied and is backing out of the contract. I sent her a message reminding her that her bid is a binding contract and let her know that I saw her bid on the other bag two hours after she won my bag. I know that eBay can't force her to pay up, but I am fuming about being lied to and that she messed up my auction. I talked to live help and they said I can't file a NPB dispute for seven days, but they also told me to contact trust & safety so they can research the issue. Besides negative feedback and her getting a NPB mark, what other recourse is there? I won't identify the bidder, but it isn't hard to find her on eBay.
