SELLING ****** VEHICLE

I bought a Toyota RunX *** from SMD BOKSBURG on the 11/06/2015. The vehicle is a code 4 OK FINE THAT I AM AWARE OF, but to my surprise yesterday the police raided our place took me and the car in saying the car is a clone and upon arriving at the station while checking the engine number they discovered the car to be a ****** and that the numbers had been tempered with as it was cut and joined where the tag is situated. Don't you guys do a back ground check on vehicles or something, the police took the car and said they will be in contact with me for further investigation. How do I answer and who must I deal with in order to get my money back and for you guys to answer to the police about this vehicle.
