Standard Bank's faltering login method is so frustrating!

What is wrong with their login methodologies? Some time ago, after logging in, their web site asked for the card number/password associated with the account. Fair enough. But whatever I entered was rejected. Had to visit a branch which sorted it out. Now, a few weeks later, the identical card/password issue occurred despite me using the SB branch solution. In addition, an error message occurred on the SB website that stated the banking credentials on iOS phone SB app did not match the internet banking version. What now!?

As for scanning in the QR code with the phone's camera, forget it, a 404 page appears every time.

Whilst I appreciate that security features are very important, but please coders, stick to one fool-proof login script and methodology, without changing it willy-nilly much to the frustration of your clients.
