Can't activate peacock subscription

When I go to xfinity.com/yoursubscriptions it says that Peacock Premium is included in my plan. When I hit the "Manage subscriptions" button it says "We're sorry. Please contact us and one of our friendly and knowledgeable representatives can help." When I click the "contact us" link it just takes me to a generic help page, which isn't useful for this problem.

How can I activate the Peacock subscription?
