poor service, no feedback and car not serviced

Took my car in for service at around 6:45 and was the second to arrive, Samantha struggled to get authorization from the plan company because the Vin number was captured incorrectly by liquid capital but the error was then rectified, she didn't bother to keep me informed on progress with liquid capital and as to whether my car was taken into the workshop, I called her time and again to find out what is the status of my car and my calls were literally hung up by the lady who was standing in for her. I went back to the service center at 15:00 and nothing had been done on my car, I took my car and left , she didn't even bother to contact me to tell me what had transpired and why my car hadn't been serviced. So I had wasted a full day and my petrol. This is not the first I received nonsensical service from this company in menlyn. I have however booked my car in at Suzuki menlyn
