Misrepresentation Hyubdai Zambesi

I bought an IX35 1.7 CRDI 2014 model on November 2019 from the above dealership.i bought the vehicle through my employer who bought it cash on my behalf. I also had some extras which are also paid for as well as extended warranty and servive plan. On the 04 May 2020 a warning light appeared on the dashboard of the vehicle and I drove straight to the dealership and was told to book it in of which i did. An sms was sent to my employer informing her that the problem is/was the turbo charge. The cost according to the sms was that it will be covered by the extended warranty. To my suprise on the 11 May 2020 i received a call informing me that the quotation is R60865 and the extended warranty will only pay R8000 and the rest must be paid by me. I was amazed because it was a different message sent to my employer. My problem is: The vehicle is still under the cooling off period of six months since i bought it. It is supposed to be the responsibility of the dealership to repair it. It appeared to me that the car was faulty when i bought it and it was a matter of time before i had a breakdown. Secondly, the extended warranty i took out is on their premises and i believed that is part of rhe dealership. Having said that I send an email to the sales person who sold me the vehicle and told him to arrange that the vihicle to be repaired or replace for reasons mentioned above. I then received a call from a Kagiso who introduced himself as the manager for the used department. He told me that there is nothing they can do except to negotiate a discount from the extended warranty people. From the email he sent I could see that he copied the principal dealership and the extended warranty people. I refused the payment for reasons above and I also refused to come fetch the car because I said to them that I fear that driving the car will cause more damage. I feel that I was misrepresented and the dealership is only interested in my money. There is already hostility between us and I do not trust them anymore. Yesterday, the 10 May 2020 I received an sms informing me that Esse Hugo will call me during the course of the day, up until now I have not received a call from anyone. I am aware of the Consumer Protection Act. All i want from them is to repair the vehicle or replace it at their expenses. The registration of the vehicle is DJ83PPGP. I really need a car because I am an essential worker and I cannot do anything without a car. The dealership does not take me seriously and for them I am just another customer. Please help.
