If you have lost your card, you have the following options in the "Cards" section:
a. You can freeze your card by activating the "Freeze Card" option. This way, you will not be able to make any kind of transactions until you unfreeze your card through the payzy app, in case you find it.
b. If you are sure that you no longer have the card in your possession, you can declare a loss/theft to cancel your card and then proceed to issue a new card.
