The worst customer service ever from Wilhemina matlawe from Standard bank

I went to Standard bank Rosebank on 03/11/2020 to have some reversal done on My Mo account which had been priced incorrectly. Fair enough when I got there my ticket was E13 and sat waiting for my turn and it showed on the ticket screen that I was next at enquiries. As I was sitting there I saw Wilhelmina Matlawe who was sitting at cubicle 2 go to another customer who came after me asked him to show her his ticket number. I could tell that they know each other on a personal level or maybe he is a regular. By then she was with another customer whom she walked out with out of the branch and on her return she asked that man to come to her. I asked her why she was not going according to the ticket system and she said there are plenty of enquiry desks. The attitude she used against me was out of total disrespect to me as a customer and as a black person. I am sure that had it been a white person she wouldn't have behaved in such a way, because she knows they complain. I even asked the lady who would help me at number 10 to call the manager and she referred me to Daniel. I told him what had happened and he left. He also never came back to me to tell me what had happened with this matter. I am deeply upset and horrified by Welheminah behaviour towards me. She lacks empathy, has no manners and is down right rude and I want her dealt with. I am sure she has done this plenty of times before and got away with it.
