They damage cars and dont take responsibility

In 2019, I encountered a problem with my car, it was revving on its own, and the engine check light was on. I booked an inspection at VW Wonderboom and was informed that the throttle body needed to be replaced. Unfortunately, my extended warranty didn’t cover this, so I had to bear the costs. A new throttle body was installed, but the same issue persisted the next day. I returned the car and another new throttle body was put in, yet the problem continued. The car frequently went in and out of the workshop, sometimes staying overnight without them identifying the problem. They even stripped the wiring thinking it was the issue, but still, it wasn't fixed. One day, the car returned with a noise coming from the front, especially when the air conditioner was on. When I took it back, it was discovered that the aircon fan was broken, which they had damaged while repeatedly removing and reinstalling the throttle body. I reported the issue, but they didn’t take accountability. I then took the car to VW Hatfield, where they managed to fix it; the problem was with the intake valve, which was causing the check engine light to turn on.

Fast forward to February 2024, I decided to take my car to VW Wonderboom (big mistake) for service since it was closer to me. They offered to do wheel alignment and balancing and I agreed. Normally, the car is ready by 1 PM, but that day it remained there the entire day. I called them around 4 PM because I needed the car for errands. I was told the car was not ready and when I arrived at 5 PM, it was still not ready. I waited another 30 minutes before I got my car back. After the service, the car started having tire pressure problems on the front wheels. I checked for tire leaks by pouring soap water on the tyres, but found none. The car would shake immensely when reaching a speed of 90kmph. I took my car to independent tyre specialists and it was confirmed that the two front mag rims were cracked and bent, and the tires were damaged. Upon inspection, they stated that the damage was caused by a machine from the last wheel balancing(which was at VW Wonderboom). I now have to spend a fortune to fix the mess that this VW made.

The mag rims damage was not the only issue. A few weeks after the service, while driving, I received a temperature warning indicating that the car needed water refill which I had to do myself. This confirms that the water was not refilled during the service. The car does not have any indication of water leakage. I wonder what other problems I am yet to uncover.
