Flysafair East London. Useless staff!

I would like to say that I have been flying with flysafair for many years as I live in Durban and worked in Johannesburg and now in East London. The Staff in East London are very lazy and unhelpful to say the least. They are more helpful towards their own race and less helpful to other races. A manager named Ballard and a lady sitting at help desk were very rude and unconcerned about me. Yesterday I arrived 50 mins before my flight to Durban only for the staff to tell me I missed my flight. The plane was still on the ground and they refused to let me board the plane. So I had to change my flight to today with an additional charge of R500. Let alone my uber charges to and from home. I arrive at the airport today the 28th of April 2 hours earlier as told only to sit and look at the empty airport.

That isn't my issue. Today I am on the flight to Durban and I see people boarding the plane at 10 to 12 and the flight is scheduled to leave at 12.

5 people came onto the plane 15 minutes before departure and 1 even 5 minutes before departure.

I want to know how is that fair? Yet yesterday I was 50 minutes before my flight only for those useless staff to say I missed my flight and I need to pay for the next flight.

This is very disturbing and I would like another airline to be implemented to do flights to Durban and Johannesburg from King Paolo Airport as flysafair here are pathetic and very race driven. Unfair and unjust.

Please advise me as how does other people get preferential treatment over others?
