I sold a higher end item to someone that has only 3 feedbacks, I accept checks and money orders along with paypal. It has been 1 month and I still haven't received her money order. She keeps saying "what am I suppose to do, I sent the check" I know she is lying but I keep giving her the benefit of the doubt. Can't she stop payment on a money order? I opened a dispute a few weeks ago, should I just close it a leave her negative feedback?
