I traded uppers with a guy in indiana( I'm in AZ) I sent mine to him pretty much as soon as I got off the phone that was almost a month ago first it was " I got your upper today ,It looks great ,but the post office says you refused delivery on mine and they're sending it back" I investigated at the P.O. they said there was no delivery. I wait about two weeks for it to get back to him ,He says it never came so he says he does an ins. claim and he could send me this other upper he has, I actually like this new one better so I say "go for it" that was about two weeks ago and I got nothing and now he doesn't answer his phone or respond to emails. I'm willing to leave open the possibillity that something happened to make him operate this way ( maybe he had something catastrophic happen ie family death or personal illness) but if he doesn't come around what recourse do I have . Sorry for the long post, but I really could use some advise
