Complain about Anglo car dealership in Binoni.

Hi. On the 1st of February 2024 I went to Anglo car dealership in Benoni, I bought a car which is a Renault sandero stepway for 95000 cash. On the very same day on my way back from Benoni to Katlehong in the Eastrand the car started to give me problem of switching off. Tried to contact the dealership but it was after office hours. The following day took the car for diagnosis to find out that the car has a problem of cylinder head casket and it has mixed oil already. To my astonishment I once againg called the dealership to tell them about the problem. They told me there's nothing that they can do because I bought the car cash. South African law doesn't longer allow for dealers to sell cars on footstoot. The car has caused me +- R200.00 now trying to fix it. The dealers are not taking my calls anymore.
