In order to refund a credit card charge made in CMS you will need to go to Authorize.net's website.
If the charge did not settle yet, you can VOID the charge (it will not appear on the donor's cc statement). If it already settled, you need to post a credit.
After voiding/crediting the charge, you can delete the payment in CMS.
