Worse service ever

I have received the worse experience with the Hyundai Pietermaritzburg branch, I am appalled. Today I took my car for a service, alright fine. Throughout the day no communication whatsoever was made with me so in the afternoon just after 16h00 I called their office to find out the status of my car and I was told that they were busy working on it I would get a call when it was ready. So I waited and no call was made. When I knocked off work at 18h00 I went there thinking OK fine if they were still busy with it I would wait there. To my surprise when I got there there was no one. No one bothered to call me to update me on the status of my vehicle nor to come and come it up if they did finish it. Now I'm left stranded with no car the least they could have done is inform me whether I could come and get my car or not
