Bad service from Audi West rand

I have never been so frustrated with Audi west rand its like they don't take their service serious. On the 29th of September 2022 I took my car for new brake pads and aircon regas, I have been experiencing problems since then. I took my car back from then on the 2nd of December to fix the problem only for my aircorn to work for 3 days and my brake pads are still squeaky and they reported that they put paint mark to check what could be the aircon problem. On the 03 of January 2023 I took my car to audi Newcastle only to hear there was no paint and they have to do it and it was unfortunate that I had to come back to Gauteng so I can not wait for their promised time.... I regret taking my car to audi west rand.
