Even if he weren't giving you the run-around or trying to ignore you (which IMO it appears he's doing both), there are a few things you can take from this:
1) Based on those ICQ logs, he has zero professionalism in the way he speaks to people.
2) There is no need to EVER transfer your domain to someone like this (unless it's part of the contracted agreement, so that you can't screw the program once the site is up and being promoted)
3) Cut your losses (I hope the domain wasn't premium) and just get someone else to get your site up. I know some guys I can refer you to if you need.
Oh and I agree with Sly; I never trust a guy who says "trust me"
