Discovery Bank - Clueless Poorly Trained Consultants

Try to access by Discovery banking app but cannot do so because the app has not sent me a message to take a selfie for future identification. This technical problem occurs every few months sand when I report the matter on the phone the consultants do not understand what I'm referring to as they have such poor training and not idea how the app works. Even tired to complain on Discovery Facebook but to no avail, same untrained clueless consultants .I seriously have to think of changing my bank. Can't go on this way !!!!
