Last night I "won" an auction for a new Hartke xk-5 aluminum neck bass. This morning, the seller emails me this ... >hey, you just won the bass in my auction. I am very sorry to inform you that as it was being transported here, there was an unfortanate incident where the bass fell out the car and cracked by the neck. I do not want to ship this out because I stated that this bass was new, and I am very sorry but my luck has been bad lately. This just happened before I got a chance to cancel the auction. I hope you understand and let me know if there is anything I can do to help this situation. Thanks! I emailed him that I didn't really believe him, that I thought the price was too low for his taste and he was backing out, but that I would buy the broken bass for $100. He hasn't emailed back. What should I do? If I leave him negative feedback, he gets to respond and gets the last word. I think he can also leave me negative feedback, which will hurt me more because I have fewer total sales.
