What is Car service for?

On the 01 October 2025 i took my car for service. A week after that i started getting a warning sign that my battery charging system is malfunctioning. I went back and i was told after paying R6 000 for service i keed to pay R1000 just for diagnosis. I found that was very unfair as when service our cars to know issues. I proceeded to change the battery thinking maybe my battery is old.

It turns out i paid for nothing for the battery. I never serviced my car anywhere else excep CMH Hatfield since i had my car. I take my car there so i have such things checked but to pay such amount for service where things are not picked up is a dissapointment.
