Misleading when buying vehicles

I bought my car in December from lifestyle motors in centurion. Had problems ever since. They refuse to take my calls or say that the manager will call back but no response. Lying to the clients by telling them the vehicle was in no previous accidents and in the meantime when you start taking your car in all the things comes out and then they will not let you talk to anyone that can help you. Be very careful when dealing with the salesman there
