Hyundai South Africa , Hyundai Benoni

I bought a car in December at Hyundai Benoni, I collected it in January it had few minor issues which I was promised when I return the car they will fix them. I took the cat ob the 8th Jan 2020 to test drive it when I return the car next weekend so that they can fox those minor issues I was told I must come during the week and all along I was communicating with them but I was not informed prior. Then I took the car back Thursday and they promised is one day service which it was not my cousin had to take a taxi back home . Then to my suprise I was told to come fetch the car Saturday and I was promised they will bring the car to me. They really inconvenienced me cos now I'm using a taxi to do my stuff in this rain.
