Locksmith Directory Scammed and attempted robbery Missouri

So today my father and I accidentally locked ourselves out of our van. Having exhausted every option we went on Google searched locksmiths and then found Locksmith Direcrory. We called and said it would be $60 dollars. The guy came down and he seemed pretty shady. He drove a white van with a pit bull inside. He then said it would cost $170. He then jokingly said if we wanted cheaper he had a hammer in his back seat. Being as we had to get somewhere quickly we paid the money and he left. That was until about a hour ago at 9 pm we saw the same guy in the same van scoping our van. When I went up there to confront him he peeled out.
