Bad interview

Last around September I was invited for an interview via teams on the day of the interview the people who were there are johannah Mokgosana who was so rude to me did not even give me a chance to even go further with the interview . She just said tell me about yourself then I did then she said no we can’t continue then interview is over ,the other people Ackerman jacques and other were quiet .She ended the meeting I then wrote a compliant which now they pushed it to Thabang Sekonyane who is an amazing person and is still assisting with this till today .it was for a post in Lynwood branch pretoria .My question is why was I invited how can they be so ******** to see all of a sudden I don’t fit the post .Johannah was extremely rude .
