If a card deposit is pending, it means that something didn't go as expected when it was authorized, so we're waiting for your bank to respond to the card deposit request.
A pending card deposit will eventually get marked as either completed or failed. It shouldn't take longer than 30 mins for a pending transaction to leave this state.
In most cases, the funds are credited to your Revolut account if the transaction was completed. However, if the transaction failed, the funds should have stayed in your bank account.
