Poor service by CarTrack Pinetown

My car was booked for fitment today at Pinetown branch,i got delays to get to the premises,but i kept called Car track office in Pinetown updating them,my car got there at half past three this afternoon,only to be told at five that technician are going now,my car can’t be fitted.Is this the best service Car track offers to customers?How can i trust car track during emergency when they can’t just help me on my first day as a customer?I understand,i am on the wrong as well for being late,but i kept updating them and scheduling my car.
