Dissapointed and depressed

Bad Day, I purchased a KIA Rio 1.2 2016 Model last year in March (2017) at Auto Pedigree Kempton Park branch. A week later I called the Manager (Thembani) and told him the car was making a funny noise. he sent someone to come and pick it up and then brought it back the following day saying there was nothing wrong with it and that is why it was certified roadworthy. My problem was the car vibrates when you start going to 120km/h and when you app**** brakes, and that there is a rattling sound in the dashboard. He said it was ok, it was probably wheel alignment; but I was still not satisfied/happy. In December last year the vibrations got worse, by March 2018 the gears were giving me problems. I tried calling him with regards to this matter and the auto shine policy but I was never able to get hold of him for the most part. I would call and leave messages for him to call me back because I was always told he's busy on the other line or out of the office, but he never got back to me. I was depressed because I really didn't have money to pay the Kia Dealership that required +/- R14 000.00 to replace the Clutch kit and brake pads. I had 2 cars before this one and I never had a clutch problem or brake pads issues. My father was even surprised when I told him I had to change the clutch kit and brake pads because he has his car for more than 10 years and never needed to change his clutch. I have been very depressed since March 2018. As a single mother with not extra cash...I had to save the little cash I had in order for me to fix my car. I was only able to do so this month when the wheels started making noise because the brake pads were finished and I started getting stuck on the road because I could not select gears. With this experience, this is the LAST TIME I ever purchase a car from Auto Pedigree. The experience has also made me to rethink buying any KIA cars ever again. I spent a lot of money on this car for the monthly instalment they are receiving.
