This pretty much. I'm mainly wondering why he invited you for something he didn't really want to do anyway. I definitly wouldn't have left home before he told me the right address and if he wouldn't awnser his phone within a few attempts I'd stop caring and go home. If I plan to do something with somebody which is kinda vague, I make sure I pick-up my phone if that person calls.
Basically, it sounds like he was just jerking you around and deserves a good punch in the face. Not sure why people think it is funny to waste other people their evening though... :S
