Penta Suzuki klerksdorp

I bought a car on the 23rd of November 2018 from Penta Suzuki in klerksdorp cash. Not even a week later I experienced problems with the Boot of the car and the sound system/ radio. I went back to inform them about the problem and they took the car in after some few hours they told me the car is fine. When I got the car back the booth was not aligned equally and the sound was still not fixed. I complained about it again and I was told that I must wait until they have settled in at the new place since they just moved they will call me. I waited the whole of December and January, went back on the 9th for the booth, it was aligned but with a space between the back light and the bumper. I had to make my own arrangements for the sound. Now I am telling them that I don't want that car anymore because I don't feel safe in it. I wanted to trade in but they can't find me something within my budget range and what I want. On top of that they are telling me of a R80000.00 refund. A slap in my face, if I knew that Suzuki sells problem cars and hide them from clients I wouldn't have gone there.
