unlimited data link error

I am looking to add unlimited data to my plan, but the link https://xfinity.com/buy/plan/checkout/XFINUDAT always directs me to an error message. Is there a way I can add unlimited data to my plan?

Thanks!

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

user_qwm9nr When you are signing in to your account to add unlimited data are you using the Primary account username and password?

Yes, I'm already signed in under my primary account. Whenever I click the link, it takes me to an error message.
