Got it, okay. Thank you for sharing that message. The link you were using is the exact one you'd need to go through the enrollment process. You would just follow the on-screen instructions to get it added. However, some accounts do have limitations to the changes they can make online (to help ensure you don't loose any special deals in the process), so this would explain the error you are getting. No worries though, my team is here to help and we can get this added on for you no problem! If you send us a private message with your full name using our peer-to-peer chat service, we'll be able to help out! Just hit the chat icon in the top right-hand corner of the screen, click "new message", type "Xfinity Support" and select that profile to send us a message directly.
