Unable to get the 299 Smartwatch Discount for being a Platinum Member

On the website and mobile app, it clearly states that 

Go to:

Login --> Membership Benefits --> Learn About Membership (scroll down to bottom of page) --> Scroll down to bottom of page and it states:

"Smartwatch discount: Limited to Xfinity Gold, Diamond, and Platinum members with account in good standing. $299.99 off for Diamond and Platinum members, $150 off for Gold members.

However, I have been to two Xfinity stores and chatted with 2 live agents and no one has been able to figure out how to get the discount.  They all state that I need to go to my Membership Benefits and add it - but that is not possible.

I would like to order the 41MM Google Pixel 5 Watch (black matte or olive) - with this discount applied.
