Faulty product and bad customer service

This car dealership is based in Sandton. I bought a 2nd hand car through financing on 5th of Feb 2020. Upon taking the car everything seemed well. I drove the car back home to Siyabuswa in Mpumalanga about 2h15 minutes drive. The following day around 21h30 I went to the petrol station about 5mins to my house the warning of the engine light came on.

I took a video of that nd I sent it to them they told me that might be the sensor so it should bring it for a repair. Thereafter a day passed the car started smoking. We arranged for a repair with them and they did. So I went up again to collect it the car worked fine with no problem whatsoever.

But 4 days later the engine light came on again. The car was overheating and then worst one of the bad day it engine stopped running. So my insurance company and I took the car for a diagnosis and the diagnostic report was shocking. So now they are not responding to my emails and watsapp mssgs. One of them even blocked me. I need please.
