Poor Service

I took the car in for a service on Saturday the 5th April. O was advised they open at 8am, they opened late not at 8am. Then I was only advised at the Service desk by the service consultant that I have to wait for he car as they can't drop me in Soweto. Why was I not advised this on the phone when I made my booking? So I waited. I needed a bumper slide and trunk button replaced, paid for parts and labor and advised I would call to book the car in as they said they can't do that on a Saturday. Was advised they open at 6:30am and once again, the dealership opened later than that. Got the car back late that Tuesday afternoon and was given my keys and sent on my way. I noticed the bumper keeps popping out still and called back to enquire, was advised to return this past Saturday which I did. Only to be advised once I was there that the car needs a new bumper. So when I asked for he service manager, he was off and was referred to the Sales manager instead. Polite gentleman who did try to assist but why was I not advised all this when I picked up my car on Tuesday instead of driving all the way to the dealership? The technician I spoke to was unprofessional and unapologetic, simply told me he forgot ....imagine. Truly terrible service. I am still waiting for a call from the sales manager, he had said he would call me Tuesday morning!
