Scam company in the name of Park and sell

I have sold my car via this so called dealership last year September and the owner never paid me my full amount. He has been paying me half half to date m yet to recieve my full amount. He stopped taking my calls and when I go to his shop he will promise to pay me in the coming days. If you wish to sell your car is would warn you against this park and sell guys. They still have 19k outstanding after 4 months and I don't even know what I did with the rest of the money
