Extremely Disappointed with Mercedes-Benz Pietermaritzburg Service

I am deeply disappointed by the level of abuse of the service received from Mercedes-Benz Pietermaritzburg. My mother took her car in for a routine service, and afterward discovered that the engine dipstick was missing—something she only realized when attempting to refill diesel. Despite reporting the issue promptly, the dealership provided no clear explanation, and claimed the dipstick was already missing, even though it was never noted during the service intake.

What’s worse is that my mother has unknowingly been driving the vehicle without a dipstick for nearly three months, which poses potential risks to engine health. Despite multiple follow-ups, there has been no resolution or feedback, and the communication from the dealer has been inconsistent—first denying responsibility, then promising to "look for it."

This level of negligence and poor customer service is completely unacceptable, especially given the stress and frustration it has caused, not to mention the risk to vehicle safety. We expect better from a brand like Mercedes-Benz. Can this matter be attended to? This is not the first time my mother has experienced problems with the dealer
