Peacock via Xfinity Rewards

I have been receiving Peacock as part of my Gig internet service.  It was originally supposed to expire June 30, 2025, but was extended to October 30th (today) (which is weird because everyone else I know had it extended one year).  Anyway, as it expires today I wanted to use my Xfinity rewards as a diamond tier subscriber to obtain it, but there's no way to redeem it (maybe I have to wait until tomorrow).  I tried using the xfinity chat, but the rep just kept trying to sell me more services (claiming my bill would go down from $386 to $367 when I in fact only pay $337).

Is there a way to switch over from getting peacock via gig internet to getting it via rewards without having someone trying to sell me other services?  I don't need higher speeds or a mobile phone.
