No response from MFC

I have a query with the car I bought from F&I Auto, a dealership in Benoni. I purchased the car on 20 October 2021 and I financed the car through MFC. When I bought the car I was told that the car don't have a full service history and that there was sludge on the engine. However I was told that the sludge was cleaned before I bought it. According to them the car was serviced just before I bought it.

I had my car for 3 weeks and then the gearbox broke. After a whole month of back and forth mails and several phone calls and frustration the dealership agreed to pay for the replacement of the gearbox. They also used my warranty to pay part of it. I got the car back early December 2021.

I have sent my car in for a service as I noticed that the radiator is not working properly. After the service the service centre gave me a report back to inform me that the radiator needs to be replaced, gasket also needs replacing together with a misfire that was picked up. The worst part is that the sludge on the engine is very bad and its proof that it was not cleaned as promised. I also have another oil leak on the gearbox.

I had the car for less than 6 months and that is where I decided I want to get MFC involved. The dealership is not willing to pay to remove the sludge and they are only willing to pay for 50% of the parts. No labour. I feel that its totally unfair that I should cover the cost for the repair of the car. As the car was suppose to be 100% when I bought it. This issues is not wear and tear.

I have sent this complaint to MFC as I wanted them to resolve the matter or at least let them advise on what I should do, but I did not get any response. I have email Neville Elie and Sharyl from MFC and I do not get any response from them.
