Unprofessional and extremely rude Staff Members at Standard Bank Chris Hani Crossing

I am extremely disappointed with the level of customer service at the Standard Bank branch at Chris Hani Crossing. The staff are unprofessional and highly disrespectful. I have never felt so undermined and disrespected as I did during this visit. I went to the branch to replace my bank card and received a new card along with a new PIN. I then attempted to change the PIN back to my previous one at the ATM but experienced difficulties. When I asked the security guard for assistance, he responded rudely and directed me to an ATM assistant by the surname of Zulu. Unfortunately, my experience worsened when interacting with this individual. Despite having been a loyal Standard Bank customer for over 25 years, I felt belittled and deeply upset by his attitude and behavior. After already waiting in a long queue and being referred to him for help, he insisted—very rudely—that I return to the back of the line. As an elderly customer over the age of 60 who suffers from joint pain, I explained that I had already queued, but he ignored my situation. Instead, he made inappropriate and disrespectful comments, telling me I needed to be more patient and even accusing me of “sleeping” at the ATM. He also compared the situation to government departments like Home Affairs, suggesting that long queues are normal and should be tolerated. His conduct was humiliating and made me feel insignificant and embarrassed. I would like to formally lodge a complaint against this staff member. As a long-standing customer, I am deeply dissatisfied with the treatment I received, which fell far below acceptable standards.
