Lied, stole

Mechanic (Paul) agreed to work on a truck -- carberator. I agreed to his price and he said he would get right to it. Gave him the key to the truck. Days went by, no work done on truck. Then, I can't get him to call me back, making excuses. Scam to make me pay more? Decided he didn't want to do the work? He didn't return phone calls, or let me know what he was or wasn't going to do. Now, I have to tow my truck at my expense, and this joker still has the key to the truck. I would not do business with him.
