Rude and unhelpful teller

I went into the FNB Carnival Mall to transfer money from 1 acc to another. Lindiwe Ngxcogo was helping but from the onset was rude, I told her what I wanted but went and withdraw money from my acc and handed it to me, when I told her that I can't carry that much cash that's why I want to do inter acc transfer. She started to about me to her colleague and they carried on talking about me while I stood there. then she eventually called her supervisor who was more than willing to assist. then when I left to go to enquiries, I came back and found out that had discussed me with other clients who were there and one of the clients, out of nowhere said to me I can't report her cause I would ruin her career so I came out to be the bad person and all the while she is sitting there, I told the lady that why can't she apologies herself and she said she is a child so I must be understanding. she is an adult who knew what she was doing and all she had to do was say she was sorry but went as far as discussing me with other clients and not once saying she's sorry. Not once have I yelled at her or was rude to her, even when they were discussing me I just kept looking at my phone and listened 2 them
