SMG ripping us off again

I have been driving a mini cooper from brand new since 2015. Since inception i have broken down 7 times with bmw on call. And more than 4 times driving to the dealership due to warning alerts on the car. From inception i have had issues with the car not going into gear. The records shows i have had at least 5 courtesy cars from bmw south Africa. My clutch was replaced at 30 000kms in 2017 due to car not going into gears. 300km just after the clutch change the car broke down again. In 2018 may the car broke down twice due to a drive train. Again given courtesy cars. In oct 2019 my car was booked for a normal service a week prior. En route to the dealer an alert came up stating that the clutch is overheating but safe to drive at a moderate speed. Drively to the dealer at a low speed during peak traffic. When the car arrived at mini umhlanga they informed the clutch burnt out. Now bmw south Africa has denied my claim stating that i drive negligently and dont know how to drive. I am a driver for 15years. And i never experienced any clutch issues with my vws or opel. I have experienced issues since i got the car and i even told them from the 1st instances that there is a factory fault. Also the car was recalled twice during all this for campaigns of the cars in 2015 model. So there is an issue. I am a sales rep and my job is dependent on having a road worthy vehicle. Now i cannot do my job as i have no vehicle and do not have R30k to pay for repairs that you expect your motor plan cover. The bmw south Africa agent that i have is absoutely rude and now states that i must lodge a complaint to the ombudsman's. They dont even want to listen or go through the history of all the issues i have experienced. It has been such an inconvenience to have this car for the last 4 years. Always having money to reserve on your credit car for a courtesy car. Then theres the risk of paying access on the courtesy car should anything happen. Plus in all this i still have a job to do. Explaining to your boss everytime that my car is not working taking leave etc is affecting my income.i used to be such a hard core fan of mini. I used to even buy all their branded clothes. All i require is to have my car fixed its not lying at the workshop as it is in maintenance . And the fact that the 1st clutch change was done due to the gear box which is not the case now.
