Bad experience with kilokor motors

I rented a car from kilokor motor not long a go I paid 20k for car, when I got approved they shown me a car , they told me they were going to take the car for service and painting since I had few scratches but when I picked the the car it was still not painted, I asked them if it was serviced they said it was, so I took the car even if it was not painted when I drove it for 3 days I brought it back to tell them that there was something not right, which they told me that the car was ok , so I left I 4 months time the broke radiator and mixed oil with water and they told me to bring it to their workshop for fixing and they sent me a quote that R54k and I asked them why do I have to fix the car that was not right in the first place I paid the 10k to start fixing the car and made arrangements with them on how will pay the remaining as I'm desperately don't have transportation to work, they took 2 months fixing it , I kept calling them till I said they must pay back my deposit including 10k they cancelled the contract and ****** me 30k to date I don't have the car and my money there are not good dealership be careful thank you
