Overbooked Flight

I am extremely disgusted at the service I have recieved from Kulula. On the 2nd of November I was meant to fly to Durban on flight JNCNWP at 9.30, the flight was was delayed by an hour. I tried to check in prior to departure which the website did not allow me thereafter I called the call center to be told by the agent Abongile that her system also does not allow her to check me in and she had no answer as to why the system is not allowing me to check in, I was advised to go to the airport 90 mins prior to departure only to be told that the flight is over booked & the flight is delayed, I was added to the waiting list. I waited up until the last minute of the flight which 10.30 finally there was one place. The service I received was extremely pathetic. Why didn't Kulula notify the passengers, the way the situation was handled is ridiculous. Many people cancelled their flights because of the mess up on Kulula 's end!!!!
