Not Serious about their customers

I booked my Ford Ranger in at Fury Ford Fourways weeks in advance for a service. I received an email from Ford Fury confirming my booking (243563) for the 22nd of December 2021 including reminders. I pitch there this morning to be told that there is no booking for my vehicle and that they can only book me in on Monday. The alternative was to leave the vehicle but it may not be worked on today, even after showing them the booking reference number and confirmation email. This is not acceptable. It is a total waste of my time.
