Turkish Airlines Seat Issue and Staff Rudeness

During my Turkish Airlines flight TK2826 from Istanbul to Trabzon on 02.08.2023, I requested the flight attendant to change my seat as I couldn't sit between two male passengers. She told me she could assist after all the passengers took their seats. Once everyone was seated, she said I could move to a seat in the row ahead. I moved, but another staff member rudely told me to sit in my assigned seat. When I objected, he told me to wait for the next flight and spoke to me in a humiliating manner in front of all the passengers, saying the plane was going to be delayed because of me. I said that sitting next to a female passenger shouldn't be difficult to arrange. The staff member turned and walked away without even looking back. Other staff members didn't say a word. One of the passengers kindly offered to switch seats with me. I have been a customer of Turkish Airlines, but I am very disappointed with such rude behavior from the staff. This is 100% customer dissatisfaction. I am very upset and will not choose Turkish Airlines again.
