Bad service and salesman lies

Worst **** ever, we bought Hyundai accent at 45 000 km, and the salesman said the car has a service plan up to 200 000km or u years. At 100 000km, we were told the next service will be on us , the salesman was dishonest and the car we bought was a demo and it was not welltaken care of, the screen has a chip, tyres were 40% at the time of sale and the car costed R250k... Radio died in November 2023, we enquired with them and they said the said is covered only up until 60 000k/m...we bought the car at 45 000 km.... Hyundai is worst and they quoted me R20 000 to fix the radio that came with the car... Hyundai is not ready in South Africa... people should go for Kia at least
