Last month, I sold a bunch of textbooks on eBay. About a week after I shipped them, I received notice that one of the buyers was potentially fraudulent, and that he deleted his eBay account. I couldn't really do anything, since I had already shipped the books out.
This morning (4 weeks after shipping the books), I get an email from eBay saying the guy opened a case against me, and he claims to have not received the book. I promptly reply with a scanned copy of the receipt from the post office, and no tracking number, just proof that I sent the book via media mail. Minutes later, he closes the case, no further questions asked.
After going back to his eBay page, it showed that he went from having no feedback within the last 12 months, to having almost 30 within the past month. Originally he had about 20 positive feedback points but those were over a year ago. My guess is, I wasn't the only person he tried to dupe.
My question is, should I contact the postal police and provide them with this information? It's pretty obvious that it was a hacked eBay account, and the guy used it to try and scam a bunch of people. I wasnt affected, but he might be able to get some undeserved refunds from some other unlucky sellers.
