Poor workmanship, no ownership, no TCF, bad service, rude staff

I purchased the i20 from Hyundai Pinetown in Dec 2021, less than 6 months later, the car started giving problems, I took the car to Hyundai Centurion and they said the problem is the oxygen sensors, within a day the car was repaired. Shortly after I had to take a trip to Durban from Centurion, only to find that the car is still giving me problems. I am really disappointed in the service I have received from Hyundai, Pinetown staff are rude, there was no courtesy vehicle, a week later I was still stranded and inconvenienced without a car, I had to keep calling to find out whats wrong with the car, on day 5 I was told by Pinetown, that Centurion put the wrong part in the car and they are to blame. The worst part is that I had to spend R2800 on petrol going down when I could have spent less than R1200 on the trip, no apology, no talk of compensation for their fault. I will not refer anyone to this dealership as they are only interested in sales and leave a customer hanging post sale. Terrible service!
