Disgusting behavior

On Wednesday 1/11/2023, I boarded a Flysafair flight to JHB leaving at 06:15 from King Shaka International airport, flight number FA411. Upon boarding, I produced a copy of my ID as my original ID was ****** 2 weeks back. I was boarded on by the friendly staff, hassle free. On Wednesday afternoon, flight FA268, leaving ORTI at 18:20 to KSIA was one of the most embarrassing encounters of my life. I got to the terminal to board at approximately 17:55, there was an attendant at each of the 2 counters. I walked to the right counter and produced my boarding pass and the copy of my ID, the lady with the glasses at that counter looked up at me and rudely admonished me telling me the copy of my ID was not a valid document. I rep**** with, "not an issue, I do have my license on me" I get a terse reply of "Well, I hope it's valid and move out of the way while you sort yourself out". My brother and my brother-in-law , travelling with me, proceeded to check through the gate and wait for me and I rejoined the line to the gate. I get to the lady again, this time with my boarding pass and a valid drivers license, she scans my boarding pass, asks me to pronounce my name, looks at my license and hands my phone and license back to me. I proceed through the gate and take my seat in the plane next to my 2 fellow travelers. The flight fills up, and right about when the crew is about to close the cabin doors, I see the lady from the boarding counter pointing and shouting at me from the front of the plane.The rude dismissive, no customer training lady with the glasses. She approached me with a crew member and at the top of her lungs in the middle (row24) of a completely full plane asked me what am I doing on the plane. At first I was confused, but she went on screaming that she didn't board me onto the plane and I am there *******ly. She then screamed out I dont have legal documents. So I tried to rationally tell her that I gave her my drivers license and my boarding pass and she let me through. She then demanded to see my boarding pass once more, naturally my phone was already in my backpack, I then opened my back pack to hand her my Boarding pass and she PUT HER HANDS INTO MY BAG AND REMOVED THE COPY OF ID AND SAID I TOLD YOU THAT YOU'RE DOCUMENTS WERE NOT LEGAL. At this point the entire plane load of passengers were staring me and I meekly once again showed this woman my license. She said I must wait and shes going to check on the system. There was no further checks done because as she immediately left the plane, cabin doors were closed and were moving. I frequently fly on Flysafair, I also only use the airline for my family and friends tickets I purchase. Is this how your staff treats people? Like we are common *******? I was embarrassed, never apologized to by Ms Glasses, my family travelling with me was embarrassed. I have to wonder, from all the passengers flying, why was I singled out by this rude , atrocious staff member. Check the footage at gate D8 on Wednesday when I boarded, to in fact know that your staff member is absolutely disgusting and she singled me out from all the other passengers. It was one thing to ask for another form of identification, but to come aboard the airline and scream at me like I'm a Fugitive is not on. I demand to know why this staff member behaved in this vile manner. And how is it that different rules for identification at different airports apply WITH THE SAME AIRLINE? It should be one standard across the board. I wait in anticipation for your reply.
