FNB please help me urgently!

Hi FNB! I desperately need your help urgently.... I have been a customer of the bank for a long time and have been using my card overseas on numerous occasions before COVID with no issues whatsoever. Now, for the first time since lockdown I am overseas again and didn't know about this requirement that I should have informed the bank prior to leaving SA that I intend to use my card overseas. I am now in Amsterdam (arrived here on Sunday) and everything was fine until yesterday (Tuesday) afternoon, when my card got blocked. I have spent the whole day on the phone with the call centre, being transferred from department to department with no resolution yet. Since COVID no vendor in Amsterdam accepts cash anymore so I am basically stuck. Can you help me unblock the card urgently? Thank you!
