Terrible Service From Airport Hyundai (Kempton Park)

I bought Hyundai Tucson ( FP 11 RH GP) from Airport Hyundai in Kempton Park last year, it has traveled 40 000 km, it gave me a problem today (03/04/2018) , it had an engine light on dashboard and it couldn't accelerate more than 80 km/h , I then took it to Airport Hyundai, the service I received was shockingly poor, I was not only shocked that they didn't give me a courtesy car but when they told me that they don't do drop off I was totally confused and it was around 12h40, my job comes with a scheme car, I'm completely dependent on this car to do my job, this is more than an inconvenience . Hyundai is big brand and I don't believe that this is how they treat their customers. Can someone call me and render me a service
