Hyundai Pinetown Worst Service ever with the service people

I’m very frustrated with the service I received today at Hyundai as last year I took in my car for a service which was due, I was then told that my car needs to be changed a few things including the service of the aircon which needed to be done everything was written down for me and stapled in the service paper. I then told Lees who was assisting me that I won’t be able to service my aircon yet I had no funds bt will book it in as soon as I’m ready. Fast forward I booked my car in around December 2020 for the service of the aircon when I had funds when I had arrived to pick up my car I I was told that a compressor needs to be changed and it will cost over 37 k Hence I wasn’t told about a compressor I was told abt regas I go to them and question them as my car was still under warranty when it was taken in and why wasn’t it sorted out hence I know nothing abt cars I take my car to them as professionals yet today a guy named Craig Asked me stupid questions abt when my aircon stopped working Who does that yet a when I took it in I was told it needs service so clearly it was before September. I’m very frustrated and will take this Matter further . Iv also sent a complain with Hyundai South Africa and waiting for a call I need to get to the bottom of this
