Terrible service

I purchased a Renualt Kiger in June 2025, my service warning just went on indicating the car is due for a service within 30 days, now 26 days. I then scheduled an appointment to have the car serviced and to get a health check done last week Thursday 14/05/2026 at Renault Parow. The booking was then confirmed on Friday 15/05/2026 for Monday 18/05/2026

I get there at 07:30, just to be told they cannot get approval as the system says too early to service, however my service warning is saying service due within 30 days

This is not great service as this should have been checked when I made the booking as it leaf to me driving out petrol for no reason and also wasted my time.

I would like to understand in which period should the vehicle be taken for a service? I would also like to understand why I cannot take my car for a service ahead of this period?

Can you please get someone to call me so I can get information around this
