Hi - I am in same position and also had the same problem.
The response I finally got (some days later, and only after my Private Banker had intervened to get a solution) - was that it is only the card that was first used to create your online banking profile that is required (not the card currently in use) - and the PIN for that card - that will enable you to proceed.
You have mentioned that you don't have those - I found I was able to access my bank account via the Standard Bank app using my SA mobile phone and then this additional login was not required. It was not very convinient doing everything on the app.
So if you have already linked your South African mobile phone to internet banking then you can access your account via the app.
If you do not have a South African mobile phone already linked to your account then I'm afriad you won't be able to use the app and without the original card /PIN combination then you are effectivly locked out until SB either (i) change your profile to replace the old card number with your current card number, or (ii) actively remove the check - which from the other psost is something that they will not do.
I hope you have your SA phone and it is linked to your account !
PS - I eventually found that once I was accessing my bank via the app then the requirement to enter the card/PIN combination was removed, BUT it was replaced with a requirement to then always have my SA mobile with the app available to validate the QR code that replaces it. So now I must carry my SA mobile with me when outside of the country just to be able to use internet banking, but unfortunatley this 2 factor authentication is commonplace, my UK bank also requires their banking app to be active when using internet banking from a laptop.
