Disappointed in Park Ford Dealership

So I took my Ford Eco Sport for a major service (6th Annual service) in January 2023 at Park Ford in Vanderbijlpark. A month later, I am experiencing engine problems with my car. Problems that I have never encountered with my car before. My car is only 6 years old, with very low mileage. When I called the dealership they were not really interested in helping me.

I am so heartbroken. I took good care of my car but now all my efforts have gone in vein.
