Poor King Price, King Cab service

Had a very unpleasant dealing with King Price. They advertise their King Cab service as operating within 50km from Pretoria City Center. When I tried to book a King Cab, 22km outside of Pretoria City Center, they told me that they cant assist me as they say they are not operating in that area. Why then advertise it as such? When I try to speak to an agent they just keep transferring me and no one actually assist to solve the issue. I wont recommended using their King Cab.
