Unhappy customer

I would like to lodge my complaint about my experience with standard bank Galleria yesterday on the 08/04/2026 around 9h15, I was in standard bank in Galleria mall, I helped by a lady whose surname is Dladla, I didn't recognized her name. That lady was mistreated me very bad, the way she spoke to me was not well, She didn't helped me with courtesy, actually I had a problem with my app that wasn't opening, when I told her the first response was what did I do with the app because it's shouldn't be not opening, an attitude that she revealed to me was very bad, I bank with standard bank for more than 20yrs, I never been treated that way.
