Well last time I heard fraud was illegal in every state, even Texas. I would suggest you first contact the owner and see if this can be corrected at this level. Odds are not in favor of this thing happening.
What ever you do DONT threaten him, punch him out or smash windows, do it all legally. Check with the local court house, they can point you in the right direction.
I got screwed in a car deal once, took it to court and he never showed, I won by default and I didnt even need a lawyer. Next I filed to have his wages attached and for him to pay court cost. Yes I got my money but it took a while. I learned alot. Good luck
