Flysafair delays and no assistance

Had an important meeting in Johannesburg and chose to fly Safair (since I was led to believe that they are the most on-time airline) from Cape Town on 19 September 2018. The flight was scheduled to depart 8:30 and around 8am the display showed that the flight had been delayed till 10:30. I immediately phoned the Safair call centre as I had a board meeting to attend at 12:30 in Pretoria, the Safair agents feedback was that she could not do anything and that I have to phone the agent who booked the ticked, I then phoned the my agent who told me that they should be able to make changes! Ultimately I had to go back, book another ticket with another airline to be on a 9am flight so that I can be in time for my meeting. Apart from my bad experience with FlySafair additional cost had been incurred because of their delays. The experience was just not good.
