Can't get Reward of Peacock Premium to "attach" to my existing 'free' Peacock account

I had a Peacock Premium Plus account prior to July 26th. It reverted to the 'free' level after July 26th.

I am a Platinum-level rewards Xfinity subscriber, and therefore eligible for a Peacock Premium (not Plus, I understand) account.

In my Rewards section of my Xfinity account, it lists the Peacock Premium reward as an item under "My Activity," and when I click on it, it says "Claimed." And then suggests the chatbot for more info. The Chatbot is useless, of course, and I still have no way to link my existing Peacock account with my Xfinity reward.

How can I have my Peacock account 'upgraded' to a Peacock Premium account? All the forums and help articles say to send a direct message to support, but the direct message function no longer seems to exist.

Thank you.
