If you find that you need to end a recurring donation or pledge, you can do that easily from your GiveCentral account. Just log in and click the trash-can icon next to the donation you need to end. Confirm that you want to remove the event, and no further gifts will be made. You will receive an email confirmation as well.
For large appeals and pledge funds, you may need to contact the receiving charity directly if you wish to modify your giving. If this is the case, we can provide contact information easily; just contact firstname.lastname@example.org with the name of your pledge.
