Dishonest and ****** car dealership

I bought a car last on 30 September 2020 , upon buying it I ask the sales lady Denise if the was not previously involved in an accident as I saw misaligned on the front bumper and she said no maybe it was just a dent on the bumper. When driving the car home the front passenger airbag came on and as I started the car I felt that the engine mount was damage. I took the car back and collected it after two week. The engine mount and bumper was not aligned as promised. I requested a dekra report from the dealer as I started to notice more signs that the car was previously involved in an accident. The dealer ignored my mails, I than decided to take the car to Dekra for myself on November and the report revealed that car was previously involved in an accident. I mailed the dealer the report and informed that same airbag signs was on again , he ignored my mails again. When called he said he will send someone to Northern Cape to confirm what's on the report. 3 weeks passed without him sending anyone I than decided to drive to him that was on the 21 December 2020. When I arrived he was no where to found. When the sales lady called him he said she can takes the pics of my complains. I was told that I will be called to discuss a way forward. Up to date I haven't received any call from the dealer. I am now driving with a car that has airbag sign on and worn out engine mount.
