Revolut payment blocked by security system
Possible fraud, so the card is frozen
Revolut's security system declines a payment it thinks may be fraud and can freeze the card or block the merchant. Payments stay declined until you answer the questionnaire in the app.
How to fix it
Open the tile on the Revolut home screen, the push notification or the email to reach the questionnaire.
Confirm whether the payment was yours.
If it was yours, the card is unfrozen and you can retry the payment.
If a merchant was blocked, choose to unblock it and then retry.
If you terminated the card by mistake, reactivate it from the card icon on Home.
