Shortly before Christmas I sold an iPhone via the website swappa.com. Lat Sunday the buyer submitted a claim that he did not authorize the purchase. I did everything I was supposed to do as a seller, shipped immediately with insurance. The packaged was received and signed for. I even can show him asking when it would ship and providing positive feedback for me. My account now has a hold on it! I've responded to the case and given tracking info and screenshots. What are chances I get screwed? How do I fight this as a seller who did everything right? What liability does Swappa have her for allowing as scammer to purchase the device?
