Free Unlimited for Veterans

Figured this would be better here. I received an email of the new benefits for Veterans. One of the benefits is Free unlimited for a year. I am already bundled with TV, Internet, voice, and cellular. When I went to the store no one knew anything about it, only add a line and get 1 line free for a year. I need assistance changing from my current plan to the Free Unlimited for a Year plan.

Thank you.
