Standard Bank - what a bunch of *********** wasters!

Standard Bank service and efficiency has been degrading for the last few years. My complaints fall on deaf ears. Today there was an issue with their new banking interface and their app, so I could not transact. I sat on hold to their useless Call Center for over 15 minutes - we are experiencing high call volumes excuse- and eventually requested a callback. The high call volume already tells you I am not the only customer having issues with Standard Bank! An arrogant female called me back a few HOURS later. She refused to listen to or understand the issue I was describing. When I told her she was not helping me and that I was sick and tired of the constant Standard Bank issues, she simply hung up on me!!! The arrogance! Is this supposed to be customer service? What gives them the right to treat customers like this? Management hides behind anonymity, thinking they are too important to speak to their clients, so I cannot contact them either. The rot stems from the top down!
