When you donate on Causes, we ask you if you'd like to make the gift a monthly recurring donation. If you select this option, you can find a list of all your recurring donations in your Account Settings at http://www.causes.com/account/recurring_donations. From there, you can cancel any of your recurring donations. 

To update the credit card information on a recurring donation, cancel the donation in your Account Settings and make another gift to the organization on Causes, selecting the Monthly Recurring Donation option and updating your credit card.
