Kulula lack of communication and service is really disappointing

I booked a flight on MN 703,the flight was initially supposed to be departure a 11:40 boarded the plane which we waited 40mins to be told there is an issue with plane and will update us another 20mins and we were told that there an issue with pipe and they will need order the part, they then off loaded the passengers which we need to go through the check in process again which was really an inconvenience as, we had to wait for about 2 hours to be told that they only managed to get some in New flights and the rest will now leave at 17:30 and you can imagine having flight at 11:40 and then to be told that you will now only leave at 17:30.At 5pm the board said we need to go to gate c9, which we should have been boarding at that time as the flight was now meant to leave at 5:30pm however there was no staff of Kulula at the gate and no communication as to what is going on, which at that time you can imagine the frustration of the passengers as well all had other appointments, commitments that we were required to be in Durban which we had to cancel due the the inconvenience caused by Kulula. At 5:30pm which was the time the flight was suppose to leave, still no site of a Kulula representative or any communication as to what is gokng on. A fly sa staff who saw the passengers frustrated and angry at this point was kind enough to get the kulua staff to come speak which they came 17:30 to tell the passengers, that he can not guarantee the flight will take off today, as he still awaiting information.The flight only ended up taking off at 18:40 which I was at the airport from 10am in the morning & the lack of communication and service was pathetic. I have return flight which I am going to cancel and change to another airline as I would not want to go to an airline which does not value their customers and its sad to say they lost a client and many more by the sounds of it. Kulula never even look at how they can compensate the passengers for this pathetic service and expect their customers to accept it which really bad service from Kulula. I wish to be compensated with a return ticket to redeem my faith in Kulula.
