I really can't leave him any feedback since I didn't purchase it through an auction. I just don't understand why he won't help. It wasn't his fault which I even told him that.Well...just really sorry how it all went down!
Have you tried to explain to the seller that you'll leave them positive feedback if they'll just help you out and give you the info? (vs. no feedback, don't threaten to leave negative feedback or they will be likely to do the same for you)
I mean, it's not like it's going to cost him a dime!
I would emphasize that you understand that it was most likely an issue with USPS crushing the box, not an issue due to their packing. If you were a little hotheaded before (understandably) then it might be better to apologize...more flies with honey and all.
I explained everything as best I could to him, but he isn't budging.
Can you do a usps claim over the phone? Maybe that way, I won't have to give them his info.
