Disappointed Audi Client

I am really disappointed in the service that I received from Audi Century City. I am a layperson wrt vehicles, but I did send an email to them when the problem was persistent only to be told that they can’t do anything as there’s no message showing on the dashboard that was 13/05/2024. As soon as the message popped up on the dashboard I took pictures and sent an email to Audi Century that this is what is showing on the dashboard. The car was booked in again on 20/05/2024, I received a call in the afternoon from the dealership that they were unable to finish fixing the vehicle they still need to attend to it the following day 21/05/2024, take into consideration that I have to take off from work all those days. I was called to say I can come pick up the vehicle. I drove from Century City with no issues past at via the fuel station to fill up, as I was driving off the message popped out again, I thought maybe the computer still needs to reset. The following day I drove to work with no issues, when I had to knock off the car couldn’t engage in any gear. I contacted Audi Century City again to report the problem I am experiencing with the vehicle that was previously attended to, they failed to diagnose the problem and solve it. They organised a Towing company to come tow the vehicle, and someone to drop me off at my house. I requested a courtesy car to be able to travel to work the following day I was told they have no vehicle though they were aware of my complaint, had the vehicle with them for 2days meaning I had to be off work for 3 days. They failed me as their client by failing to resolve the problem, endangering my life and those of the other road users. In a nutshell I can say they don’t uphold their vision, mission and values. I am disappointed, frustrated and lack words to express how I feel at the moment. Today I received a call from the service advisor I could sense some kind of attitude, explaining the problem and that still needs to fill in some paperwork to request a courtesy car for me. The vehicle in question was a demo car purchased at Somerset West Audi, only had it for one year, 6 months, mileage around 47676. I t
