Worst Customer Service Ever

My car was towed in on Saturday morning because it wasn't starting, no one from Kia called me with any update until Monday afternoon when I called. Samantha promised to call me back and she didn't, I then had to shout at the reception after leaving my number 4 times with no one returning my call, i was then transferred to Samantha. I was told my car wont be available to me for the next 10 days as they had to import the part , I called their customer care and spoke to Farane, he said they will rent a car for me and it will only be available on Tuesday. She called me on Tuesday around 12:30hrs asking whether I had received the car and I told her no. They didnt call me back after that, at 15:30, when I was about to leave I called them only to be told I wasnt gonna get a car because the part was now available, I got stuck at the office without transport to go home, I had to pay R500 for a taxi from work, pick the kids from school then home. I called Natalie complaining and she was very rude and she cut me off the phone saying she was under no obligation to provide me with the car they had promised. I spoke the dealer principal who promised to call me back today I am still waiting...
