Rejected (again) No Reason given

So once again I tried to apply for a standard bank credit card online and instantly its rejected once again. The reason given??:

Your Standard Bank Credit Card Application has been declined due to the following reason(s): Dear Valued Client, unfortunately you did not meet the minimum requirements for a Standard Bank Credit Card Credit Card.

What reason is that? What can I do to meet your requirements then?

So, WHAT is this minimum requirements and where don't I match up? Not even the branch can give me any answers on this. How can I rectify my situation if you refuse to show me exactly what the problem is? How can I fix the problems? My credit bureau report s are excellent and innthe green and no deafaults or any thing else is reflected thereon. My credit score is high and far above average . Nedbank helped me with vehicle finance and credit card. Capitec helped me with personal loan. But my own bank foe over 20 years, Standard bank refuse to approve any of thise I apply for? But WHY Thank you very much Standard bank This is how little you value your customers.
