Disappointing after sales service

Extreamly disappointing after sales. Bought a car in 2022. Car had some issues, brought it to their attention, they sorted it out but not with many inconveniences. Lots of my time had been wasted getting things sorted, I had to follow up and push to get things sorted. Once my car was not released from VW because they had sent the parts there but not arranged for payment for labour. I was told the car had a manufacturer warranty till Dec 2023. Only to find out when I took it to VW that there is no warranty. They arranged for an after market warranty, but it doesn't pay 100%. Last year I had to replace the thermostat, total cost was R15k, warranty covered R6k, I had to pay R9k. The dealer principal has Darius Steyn has been ignoring me.
