Jing Jing Du bought for hundreds of dollars merchandise from us, which we shipped with tracked priority airmail. USPS at the moment causes transit delays and did not scan it in yet, which we told her. She then filed a chargeback with as reason: "Fraudulent payment - I never bought from that store". This makes JingJing Du guilty of Mail Fraud. Our shipment can de delivered to her any moment, while we're out of hundreds of dollars.
