Private Banking with Standard Bank means nothing

As Private banking Client Standard Banks service is non existent. I have had my banker change so many times its and not being able to get hold of them. Right now I have been holding for exactly 45 minutes to get through to internet banking because the app is not working. Have Standard Bank systems have been hacked? Is our information still safe? I have had the same payment go off three times. I am trying to rectify it and the assistant is stopped in the middle of verifying my details. She is lost somewhere on the internet or on some line somewhere.
