Hyundai always messes up my car when they are suppose to be servicing the car

I am VERY unhappy with the service I always get from Hyundai Plumstead but this years service which was on the 7 December 2023 took the cake.

Firstly I want to mention that whenever I took my car for service I was always told they don't have a courtesy vehicle to drive me back to work and I always had to uber. The morning of the 7 December 2023 the service consultant Bilqees Wasserfall tells me the same story and when I go wait in the waiting room to book myself an uber, a staff member of Hyundai comes to ask the people sitting around me who is going where and there were people going to the same area as me and I had to ask to be included in the lift! When I asked Bilqees Wasserfall about this she had nothing to say.

My major complaint now is that my aircon was not blowing cold air and I asked Bilqees Wasserfall that they must look at this. She calls me to say that this would be R395.....is this not supposed to be covered by the service??!! Anyway I paid the R395 yesterday and we did all the paper work when I went to collect the car. She then walks me to my car then dumps the news on me that they damaged the compressor when they were regassing the aircon and she gave me a quote of R20 046 to fix this. She says that the radiator probably didn't have oil when they regassed it.......surely they should have have due care and checked that everything was okay before they went ahead and did the re gas now they have damaged my car's compressor and they expect me to pay them to fix it and on top of that, the aircon is still not blowing cold air so yet she took my money and didn't even have the decency to call me to tell me all this before I went to fetch the car and also not even when I got there, only told me all this when she was walking me to my car! Last year when I took my car for service to Hyundai Plumstead, they messed up the part that shows you how much petrol you have.....here I was thinking that I had petrol but meanwhile I didn't have petrol. I was driving in my car with my family when the car switched off and the car was towed because the car showed that it had petrol but it didn't because they messed up the part that shows that there is no petrol......I didn't complain about this but this year they have gone too far.
