After 3 weeks and ignored reminders, I used eBay's dispute console to report non-payment. The buyer (who admitted check was lost) left neg fb BECAUSE I used the dispute console. I requested eBay to remove it and I was told, sorry, can't--doesn't meet our removal criteria... !!!!!!!!!!!!!!!
So let me get this right... a Buyer can renig and there's nothing we can do except graciously let them cost us more money with negs.
Wow... great business model.
