I'm also waiting on a dude, last on ASC Dec 30th. He has yet to provide me with a tracking number and hasn't responded to any of my messages since I sent my payment on Dec 21, and payment cleared on the 24th. I'm giving this guy until the end of the week to get his shit sorted out before I start a thread to make a case about it and frag his trader rating.
Send your guy a message with a read receipt so that you can see if he's reading your messages and ignoring you. That's what I did today.
