Unprofessional service

I reported warning lights on the car on the 5th January 2022 and the car was booked in at Audi Centre Rivonia for the 10th January 2022 of which nothing was done regarding the warning lights on the 10th.I wasted my petrol and the whole day on the 10th.Secondly after towing the car to the Braamfontein on the 27th January 2022 after I called Audi roadside assist and my car is still not done.Their service guy told me that he tried to get hold of me but didn't have my number of which it clearly was on the job card.I am spending money on transport even though I paid Audi R 456 000.00 for the car which I only bought in February 2021 but has gone into the workshop 4 times already.So I am just wondering if Audi really takes their clients serious or if they are just happy to take the money and not care about their clients afterwards.
