Incompent staff and poor customer service

I booked my Jeep for a services at Grand Central Midrand to be on Friday 4/10/2019 and I then phoned the dealership on Wednesday 02/10/2019 to reschedule to Monday the 8/10/2019. The bookings receptionist confirmed the changes but today when I took my vehicle there they said I was never booked for today. Now they said I can leave my vehicle there but it will Tha last to be attended and I won't even get it today. Now I have to pay for the sins of *********** employee. Because now I won't a vehicle for 2 days.
