Terrible service experience

This has been the worst experience with a KIA dealership by far. I called two days ago to book my car in for a service and they didn't even register the car for the service. When I got to the dealership they added my car. Then to get told they decided suddenly to not pick up customers. This isn't something you decide on in a whim. Utterly disappointing. KIA Johannesburg South is by far the best.
