Terrible Service and bad workmanship from CMH Pinetown

I purchased a 2017 i10 last year from a sales person called Wasim. The car had a few issues but, the main, was a shudder, when I took off. I complained about this, not knowing what the issue was. I was told that there was a new clutch put into the car. There was a licencing issue but, this should not have prevented the dealership from addressing these mechanical issues. I was not, initially, advised that I had 6 months to get any issues sorted out, and even though my complaints were within this period, they were never address. He did eventually contact me a few times, but, kept saying their workshop was busy. I eventually drove there, and sat at the office waiting for him. He never showed. His manager, Shawn, drove the car and noted the shudder but, did not inform me that it could be covered by warranty, which was still active then. I also enquired about extended warranty which I never got feedback from. The clutch eventually started making a weird sound and, I took the car to a private mechanic. He noted that a bush was missing from the bearing shaft which was the cause to the shudder and, eventually the bearing broke. He also noted a sub-standard clutch was fitted. This is now setting me back R5000.
