No compassion from service staff

I've been waiting now for 3 days for them to replace my clutch kit on my Chev Cruz, without any success. Evertime, I ask them for an update, I get told that because I did not book my car in for repairs, every day it goes back to the service queue - as if I knew that my car would break down on my way to work. The Service Consultant doesn't call me back. When I called him at 14h00 on Wed, 4 Nov 2015, he told me that they are still busy working on my car but when I got there at 16h30, there was no mechanic in sight. I've explained to them that where I'm staying in Randfontein, we have no public transport and I have no other means of getting to work. My work is very strict when it comes to taking time off, however, they are not concerned about my problem and I've been told by the consultant that there is nothing he could do about it. He showed no compassion. I've experienced a similar problem with them last year where I had to wait 5 days for my car. On another occasions they refused point blank to assist me since my car was no longer under warranty and I had to tow it to another GM dealer in Jhb.
