Left in the lurch in silence

Have a premier Credit card which I have been using abroad. All of a sudden my banking app on one of my phone wants me to put in my password when I have set up and have been using biometric login as I cannot remember my complicated (SAFE) password.. Anyway to cut a long story short I try to reset my password so that I can actually login with the option that I did not choose only to be told that the card and password that I am entering for the verification process have been cancelled.. This with no notification or communication from FNB while I am abroad and unable to access funds or login to my banking.. Nice one FNB.. Still waiting for some or other communication from FNB in this regard. Whatever the reason for the cancellation is.. Some communication would be appreciated or at least expected. Rather an arrogant, heartless approach I would say..
