Kulula doesn't care

Booked a flight with Kulula to go from lanseria Airport to Durban. Flight 539 08 March to depart 20H45. Get to the airport then it is just wait and wait and a you hear is kulula apologizes for the delay. Now 22H25 and we get told the crew has only just left JHB now and should take another hour to get here and apparent departure time is now 23H30. I know very well that Kulula will not care about this review. However I will never use Kulula airlines again and anyone I meet in business I will talk about this experience and tell them to use any other airline.
