Bad Service from BMW Centurion

I phoned BMW Centurion on Monday (29/11/2021) to book a service. The receptionist told me that the person who does bookings is busy. She asked me to leave my number so that she can pass it on to the person who does bookings. It is Wednesday today (01/12/2021) and no one has called me. I had to take my car to BMW Midrand/Waterfall. Basically, I contacted them last month and they have not said anything, even in December.
