So I sold a bunch of textbooks on Half.com a couple months ago. They sold quickly and I shipped them all out on time, with no apparent problems. Now, today I get an email saying that there is a chargeback on one of the sales. Ebay says that either, 1) I didn't ship the book, or 2)The book was bought with insufficient funds. I know damn well the books were shipped. Ebay wants a tracking # to prove that they were shipped. The problem there is that my gf shipped them and doesn't have the info anymore. This was 2 fucking months ago, why would I even keep that shit around. I sent the buyer a message asking wtf is going on. Ebay is bullshit now too because sellers can no longer leave feedback, so this bitch can keep doing this shit again. Any ideas? I'm going to try calling ebay and talking to them, but I doubt I'll get anywhere with em.
