AutoNow payments will be sent out every day after 5:30pm EST. Please ensure to update your Debit card information before 5:30pm EST if it has changed. You may update the debit card information in Account Settings of your account.
It is possible that a transfer may be deposited instantly even if your debit card was cancelled. Check to see if the funds showed up in your bank account associated with the debit card.
All AutoNow transactions are final and cannot be cancelled. If the payment has already hit your bank account, you should contact that bank and ask if they can perhaps transfer your funds.
