yeah I'd be upset to. live and learn, be more careful next time. You did do a good deed for them, unfortunately they are con artists, and you probably are not the first, and won't be the last man they screw over.
Also, I'd call the police station to make sure your stuff is there before you go down, I wouldn't trust these people for shit obviously.
Did they leave your money with everything, or are you not getting that now?
