At one point years ago, I would buy and sell on EBay all the time and had a bunch of crap like that happen.
My favorite was when I bought one of those old Hamms scene o rama signs from the 60s, the big one with the waterfall, for the man cave.
The thing shows up with the roof busted and some loose interior parts. The idiot packed it like shit. He threw it in a big box with a couple of pieces of newspaper on top and shipped it, I mean ZERO protection. A total I don't give a rats ass fly by night packing job.
I had to walk through the fires of hell to get my money back, the guy was fighting it every step of the way.
After 6 weeks and numerous pictures of the damage, I finally got my money. After it was done, the guy had the balls to ask me to ship him back the sign on my dime. Needless to say, I told him to go have sex with himself. The guy sends me a reply, claiming he was going to come to town to kick my ass.
I sent him a reply back and told him, "You know my address, let me know when you can make it over, I'll be happy to host that party." I didn't hear from him again.
At this point, I rarely have anything to do with EBAY, I might buy something twice a year at most.
