Nick, I bought from the same seller. Mine landed in LA yeterday. It showed in the air since April 10. I'm curious to see if mine goes to "the wrong buyer" also. If so, I'll be dropping this order like a bad habit. I've left them alone, as I figured I'd get the same responses you got. When I initially asked for tracking 5 days after purchase I got the same answer as you did.
Next time, I guess I'll just take my chances with Jin's auctions. I wish he had a BIN too, I'd pay what the $350 they are going for to get a good engine in a reasonable amount of time.
