Unhappy client

I took my car in for service on the 25/09/24,after 2 months the car was showing service light I called to ask about this service light I was told the light was not programed, shortly there was another light coming on, I refer to the manual book to see what is that light for, it says I must take the car to the nearest dealership, I went back to Zambezi Renault they told me that the needs to be diagnosed to see what could be the issue.. Which problem in 2 months that the couldn't pick it up during the service,, now I must pay R1035 diagnostic fee,, I'm very unhappy
