Peacock Premium Reward Not Showing

I had Peacock Premium when we were subscribed to 1000gb internet. Now that I've downgraded to 800gb, we no longer have Peacock Premium. I am a Platinum Xfinity Rewards member and according to this site (https://www.xfinity.com/support/articles/peacock-premium-offers), I should be able to use the reward to get Peacock Premium. I don't have the reward. I've chatted with someone online who said I should be eligible and to call. I called and they told me I can't use the reward b/c I don't have 1000gb. The only requirements per (https://www.xfinity.com/support/articles/peacock-premium-offers) is Diamond/Platinum status and Xfinity Internet which I have.
