How to Redeem Xfinity Peacock Reward

I get this email that I can redeem a reward of Peacock premium for being a platinum Xfinity rewards member. It’s supposed to be so easy as just signing in and I have tried following email directions to no avail. The robo assistant does not help and nor does it take you to the next page to sign in. I don’t even see that reward itself on my rewards page to redeem. I’m I missing something or has the offer expired? This is why I don’t like these alleged rewards because when I do show interest and want to take advantage of the offer, it ends up being a headache to sign up or whatever.
