Don’t book services on Saturday!!!

The way I wasted my Saturday morning. I booked a service at Hyundai Weltevredenpark for a Saturday. They told me that they can’t help me because liquid capital didn’t authorize my service as yet And they can’t help me coz it’s a Saturday. Why didn’t they tell me I have to book a service during the week before I wasted my petrol. Just a warning to anyone don’t book a service on Saturday
