Banned from flying CemAir. What?!?!?!

I have been banned from flying Cemair!!!!! I have no idea why and they wont tell me. Only that their COO said so. I have experienced everything that all of you have experienced on this ********** airline! It is the worst. From delayed / cancelled flights. No refunds. Transfers in unroadworthy vehicles, buses breaking down after 12 hours trying to get home from Johannesburg to Durban. After the last mishap I dared to write a letter of complaint and have since been blocked from flying with them! Who knew complaining was a crime?! I often used to fly from Margate to Johannesburg for work. But I started driving to King Shaka instead to fly from there because of Cemair - it was less stressful to drive almost 2 hours and know your flight would be on time. This weekend my boss said I need to get to Joburg for a meeting and I thought what the heck let me try again. BAD IDEA. I couldn't book online (I later found I had been blocked) so I called their booking desk. They booked the flight. Then I couldn't pay online. I called back only to find out they spelled my name wrong. I tried again. This went on and on. Only after one of the agents sent me a link, I paid. Then I received a call from their manager to say I have been banned from their airline! I was SHOCKED! But from reading some of your comments I see now that they DO NOT CARE about customers at all. The numerous complaints of racial profiling are particularly concerning! We are trying to improve tourism and travel in SA and this is what happens! We pay their inflated prices for the "convenience" of flying from smaller hubs because they have the monopoly. I think that is why they feel they can mistreat everyone. They have the time to block me on their system but not to respond to a complaint. I am so angry. Something needs to be done about this airline.
