Unable to view or change plans. Can't look at deals

I am looking to modify my plan and/or look at deals as my promotion is almost up. When I click on the "Change Plan" link in the XFINITY App or on the XFINITY website it loads a "We're Sorry" site (https://www.xfinity.com/error/buy/sorry?errorCode=plan-contact-us) can anyone send me a patch or figure out why I am getting this error? Thank you.
