I bought Apple AirPods Pro 2 and paid for them. I asked the seller for the serial number, and he sent it to me, but it turned out they were fake. I asked him to cancel the order, but he didn't respond. I tried to cancel it, but they said it would take two days. I went to the bank and got a refund, but the order is still being shipped. I got my money back; what should I do?
