Xfinity account does not recognize that my new contact information has been verified

I recently changed both my e-mail and phone number. I changed both my e-mail and phone number on my Xfinity account, and verified both. However, when trying to add a new payment method to my account, I keep receiving the following error: 

"You can't add a new payment method yet

We need to verify your contact information to keep your account secure. Make sure to add your phone number and email address if you haven't already."

As stated, I have already verified both my new e-mail and phone number. I have tried to add a new payment method using the app, and two different web browsers. I am met with the same error message each time. Clearing my cookies and cache did not help. For whatever reason, both the app and the browser do not recognize that my new contact information has been verified. I have sent verification texts/emails to my new contact methods multiple times and verified them over and over again, but nothing changes.
