Humiliation caused by Flysafair

Yesterday the 1st of Jan 2025 I boarded the flight from Johannesburg to Port Elizabeth. I chose 9F seat and I sat there later on a lady with Menzies uniform came and asked for my boarding pass I showed her, 2 min later a guy (flight attendant) asked for my boarding pass and I asked why am I not supposed to be here why do you keep on asking for my boarding pass? And there was no answer. The 3rd person was Faith the flight attendant asking for the same thing I asked why? She said my seat is double booked. I was surprised because when I chose the seat there was no booking next to me as a result I thought I was going to be alone. She asked me to seat at 2F I was not happy with that because if I wanted I should have chose it but I chose 9F. And I felt embarrassed with the whole thing people watching me moving from my seat with my luggage as if I'm stupid I didn't know how to read. When this drama happened everyone was settled on their seats just looking at this. What a humiliation they caused me😭💔
