Platinum Rewards trying to redeem Peacock Premium

Last week I received an email that I was now an Xfinity Platinum member and that included with that was the perk of having Peacock Premium. The website says that under rewards I should see the perk and be able to claim it but I do not see it under my rewards. I contacted Customer Service and they were not able to help me, they were only trying to make me sign up for a new plan that included Peacock. I don't want to change my plan, I just want to redeem the reward. Thanks
