Williams Hunt Randburg sold me a very bad vehicle

On the 4th of April 2018 I bought a Peugeot 207 1.6 Gti from Williams Hunt Randburg with 100 000km on the Dash. On the 9th of February 2019 the car started giving me big problems when the turbo started failing, I called the sales consultant who sold me the car(Ashley) and he told me to take it to a Bosch service center as the vehicle is still under 2 year warranty. I took it Bosch service center and I had to pay R20 000 to fix the turbo as the insurance offered to me by the dealership only offered to pay R 5000 of the total R 25 000 invoice. The technicians at the service center told me that the car was not in good condition at all. Furthermore I had only driven the car for about 3000 km within a year, I had barely used the car at all I only drove it on weekends therefore the technicians informed me that Williams Hunt Randburg sold me a really bad vehicle that was not in good condition.

After paying R 20K for the recon turbo I drove the car for a few weeks and it broke down yet again, I took it back to the service center and it has been there for 5 months...for 5 months I have been paying for a car that I have not been driving and I have no transport at all. The Service Center then additionally charged me another R 6000 to further fix the turbo 3 weeks ago, after fixing the turbo they tested the vehicle and found that there is another issue with the trooper body that will cost me R 9000. Williams Hunt Randburg sold me a very bad vehicle and now I am stuck in debt with my whole life falling apart because of this.
