Jaw dropping appalling service. A nightmare Audi Centre

I have had a recurring engine light on my Audi A1 since I took it in for its 60 000km service. The light had never been on. I’ve taken it to them to fix what they broke twice before about this light and each time it’s a different answer as to what is wrong. After not receiving a call back from my Audi consultant, I called her manager who gave me a standard client apology and said I should bring the car in again. I did so this morning, the manager didn’t even care to see me in the morning. They have had the car the whole day and I have had no word from the dealership about progress on the car. It is now 6:30pm and with no word from Audi about even a courtesy car atleast, I’m stranded in Pretoria CBD with no transport to get home. A 25 year old small figured defenceless girl left stranded because no one has bothered to tell me when I can get my car back. By far, the worst service experience in my life. Clearly no care in the world to provide a customer with feedback on the only thing that transports me. Zero communications. Absolutely disgusting. Poor workmanship and no care from management. Rotten service to say the least.
