Defective new vw car

I bought a car at vw Barons in Durban in 2019 September polo vivo maxx 1.6 ever since then the car is giving me problems and i have been suffering with this so called brand new car and no one is interested in assisting me from vw side all they care about is that i must add another credit on my name by taking another car and pay more money on top of this one,and this car spend most of the time in their workshops and come back with the same problem and even more problems and this is really affecting me even physically and emotionally as the car nearly killed me on the 10th of August 2021 as it lost controll and still no one cares.

Thank you
