It's a balenciaga city. I had it authenticated here on tpf when I bought it. I decided to sell it almost immediately after buying it. Buyer receives it and says its fake. She says its missing zappo on the underside of the zipper. I've since had it authenticated by 3 of the authenticators here on TPF. She has opened a PayPal dispute! Honestly at this point I really just want it back and to refund her. I'm so worried this is a scam. What should I do!?
