Bad service and ******

I writing this with heart full of pain and regret, I bought a car at we buy cars in December 2022 I collected the car from the dealership it was a Friday the salesman name Halala was the one assisting me with the sale everything went well and he told me that the only thing that is need to do was to take the car for a service of with I did the following day, but before that the car was empty with no fuel at all I drove to the garage to fill up, few minutes after filling it the car it started making sound and showed many alarming hazard, I quickly went to car time for it to be checked the guy who assisted me told me that what ever that is writing on the car it need special attention. I drove the car and booked it for service the following day when I arrived at car time they did a diagnosis of the car and the told me that the car engine is bad the will recommend that I get a new engine or have this one fixed at the amount close to R25 000, I immediately contacted the salesman Halala he told me to write the complain on their page someone will call me after sending all the reports I got from the service at car time, I waited for weeks with no reply after sending multiple complains and sending email. until a guy name Simphiwe called after weeks I explained everything to him, and after that there was no feedback until I call him again he told me he sent the email to sales manger Ryno Herman to cancel the deal but no body called me, I went to the branch spoke to Ryno he said he knows nothing he didn't receive an email, he said we will send an email to customer service that was beginning of January 2023, he never called me back beginning of February I called Simphiwe and told me that he will organize a tow truck to come and fetch the car or if I can tow it myself will be fine and I did that, but the service I got from Ryno after bring the car was very bad he ignored me I was there from 12pm until 5pm and then he came and told me that the cant take the car he mentioned things that were not relevant and I found them invalid but I gave him a chance he promised to call me on Monday the following week and he told me that they declined the cancelation based on his invalid reasons their head office never bothered to call me and hear my side. the car was with the for the whole month of February they told me to come and collect the car an now the car is parked ever since only drove that car for 4 days after purchase and I strongly believe they took advantage just because I was a black person and the customer service person was also a black as he was also shocked why Ryno didn't not the car and allow the to take another car within the same amount because all the service paper work and diagnosis reports were legit. I am stuck with this car for 6 months now I had the turbo fixed I cause it was releasing smoke and it was not starting I really need someone who can assist me with this matter cause as a black person in this country if you will not happy with something they think you did something wrong and Ryno proved that many times.
