What bank do you have a credit card from? I know some banks block cards if you have not notified the bank that you are going abroad. And if you have a large credit card debt, it may be difficult to leave the country. By the way, there may be limits on using credit funds for online payments and payments in other countries. In any case, it is better to consult with the bank before leaving. But in your situation, you can consult a financial advisor https://katiecashonline.com/team/katie-raines/ if you can't contact your bank.

What kind of bank is this that you can't call? Or is it because you are in another country? A very unpleasant situation, of course. Now I will know that it is better to clarify everything at the bank before leaving. And I do not want such unpleasant surprises.
