Diamond Rewards Peacock benefit says my Xfinity account is already linked to another Peacock account.

I am an Xfinity Diamond Rewards member and my Xfinity account shows Peacock Premium as an available benefit with "Activation Required."

When I click Activate and attempt to link my existing Peacock account, I receive this error: 

"Your Xfinity account is already linked to another Peacock account."

I only have one peacock account. The email associated with my Peacock account is the same email address associated with my Xfinity account. I have not previously activated the Peacock benefit through this Xfinity account before attempting this activation.

I have already contacted both Xfinity and Peakcock support, but neither has been able to resolve the issue. 

I believe there is a stale or incorrect Xfinity/Peacock account association preventing the Diamond benefit from being activated. Could an Xfinity employee please investigate the Peacock entitlement/linkage on my account and determine which Peacock account Xfinity believes is currently linked? 

If necessary, I would like the existing linkage reset so I can activate the Diamond Rewards Peacock Premium benefit with my actual Peacock account. 

Please let me know if you need me to send my account information through a private message.
