Bad Service and Lack of Transparency

I bought a car in August and no car problems were addressed at a point of sale. I had to take the car back to be fixed and it took them a whole month to try and fix it to a point that not all the issues I raised were resolved. I went to collect a new disc from the municipality on 4Nov2020 and was informed by the municipality that the car was not taken for a road worthy test before it was sold to me. I contacted the dealer and spoke to Ross who was very rude towards me. Now I can't obtain a car licence renewal because the dealer did not take the car for a road worthy test.
