Okay, I posted a topic here a few weeks ago "I think I just got burned by a fellow board member, NEED HELP". I acted a fool, by jumping the gun and panicking before I needed to. I made a deal with a guy to buy his preban PWA/Bushy M4 and several accessories too include 750 rounds of American Eagle ammo. After my little tantrum, I received the rifle and the accessories, but not the ammo. He sent me an email stating that he wanted to send the ammo separate to cut down on shipping costs. He said he would ship it on the 28th of April. Because I felt bad about my behavior, I sent him $20 to help out with the shipping on the ammo. I have heard nothing from him and have sent him 3 emails with no reply. This is going on 12 days now, and frankly I don't know how much patience I'm supposed to have. What should I do?
Edited to add: Fuck it, there really is nothing that I can do about it.
