Nothing terrible will happen in most cases. But what to do next depends on what exactly is perceived under the blocked card. And there are options here.
This happens if, for example, you have stopped being a customer of the bank. Both the card and the account simply do not exist.
In this case, the money will simply be returned to the sender. It usually takes several days, exactly how much is better to find out in a particular organization where the money went. After that, the person will be able to transfer them to you again — where you need to go.
If the money is not returned within 7-10 days, the sender should contact the bank to which he transferred the amount.
If so, the money will be safely credited to the account and you will be able to receive it. But further actions will depend on the reasons for the block and how urgently you need the amount received.
For example, the card may be blocked because of the wrong PIN code entered three times. But it will "die off" itself in 24 hours, you can use it. If the card had to be frozen because it got lost, broke, or something else happened to it, you can reissue it and get access to the money again.
But if funds are needed urgently, there is always an option to take a passport and go to the bank's cash desk. There, cash will be given directly from the account.
Both the card and the account may not work for withdrawing money if the funds on it are blocked at the initiative of the court or the bailiff service. This happens if a person has alimony debts, taxes, utility bills, or some other obligations.
Sometimes the account is seized before the final decision is made in order to save money. In this case, there will be no access to them until the proceedings are over. If it is officially recognized that you owe someone something and are obliged to repay the debt, access to funds can be obtained only after payment of the penalty and related expenses. For example, if you are dealing with bailiffs, you must also pay a performance fee — 7% of the amount owed.
If there are no more obligations, but the money is still unavailable, you need to deal with those on whose initiative the ban was imposed. Namely, to provide evidence that you have paid off your debts. For example, to present a receipt or receipt confirming the transfer.
