Unreasonable service.

I bought a brand new 2024 Polo TSI from VW ballito on the 5th of September. Within a week of having it my first gear started giving me a problem which I reported to the dealership. The gear had intermittent issues where it would jam but other gears would go in just fine. This posed a large safety issue for me as I can’t just have a car that chooses to jam while I’m on the road. I took it into the shop as my sales guy had advised and the technician that test drove it didn’t have that issue. I was advised to take a video the next time it happened and I did just that and sent it. I was told to take the car back again and again I got no joy. The workshop manager made claims that imp**** it was a me problem and that he would have to experience the issue himself in order for me to be helped. This is obviously unreasonable considering that I’ve reported the issue twice and took a video as evidence. I escalated the issue to VW South Africa and I was told to wait 24-48 hours. I still have not been assisted. I’ve been stuck countless times yet I bought a new car.
