Hi folks! The best way to take care of these changes are going to be via phone at 1-800-595-4401 or via email at firstname.lastname@example.org .
Please be prepared or send along some information for verification. We can accept a recent invoice number or the last 4 digits of the credit card we have on file as verification. For security, please do not post that information here since this is a public forum. Once verified, we can update the admin and/or billing credentials to whatever you need.
