Horrible Customer experience and Car service

I am so disappointed with the service I received from Ford Alberton I booked in my car for service on the 10.12.2021 on the same day after the car has been serviced, on my way driving back home the Gear Lever broke, it was too late to call the dealer as they were closed. I called the dealer first thing in the morning & I was told that I they fully booked I won't get assistance & told the open slot is for the following week on Wednesday the 10.12.2021 I asked Thembi to make a plan she said unfortunately there's nothing she can do. As disappointed as I was I drove thinking it might be something minor & I realized that the Gear Lever is now way to loose & started making a funny noise. I called back and asked Thembi that this must be taken as an emergency @ that time it was around 11:30am she said the technicians are closing @ 12pm & they won't be able to assist, I further ask that she needs to change the slot from Wednesday to Monday first thing in the morning and she did. I asked how long will it take as I use my car for work & the (Service Lady) didn't take her name taking in the car said 3 working days I asked her if they will be providing a courtesy car she said no only if it's more than 5days:( Disappointed as I was I made arrangements for the 2 days, the next morning Tuesday the 10.12.2021 Ayanda calls & tells me that the Foreman Fanie says he will charge me R4900 to fix the car. 1. I asked who must be liable for the charges when I booked in the car & during the service I was only told that the wipes are not in good condition no one said anything about the Gear Lever. 2. How is it that the person servicing the car didn't pick up the faulty Gear Lever? 3. The car had no issues until I left the dealership & after the car has been serviced. I was confident that I will be safe on the road only to get my car broken. 4. I travel with a 13 year old on a daily basis so our lives are at risk because clearly things are not done properly. 5. I do not have that kind of money hence I pay a service provider for this service. They told me that they giving me 15% from Ayanda's side and the foreman side as a way of acknowledging their fault but still charged me for their in competency. I refused and the foreman gave me a call & said he will call me back. He definitely called back & said he managed to bring the amount down to R2766 unhappy and frustrated as I was I didn't argue with him and I was really upset.
