Discovering new ways to BANK

I have been trying to update my contact details with Discovery since they moved their credit card facility from FNB so that I can login and get details for my various accounts. No luck whatsoever. This is beyond pathetic. Best is today I am informed that they can't update details because I am 3 days late on a payment when I made an arrangement to pay on the 20th each month until December 2020 due to C19.
