Peacock Premium stopped working when services transferred to new address, says Xfinity account is already linked to another account.

I recently moved to a new unit within my building, and had "new" service activated with a new Xfinity account number (same plan, just a different unit in the building). Now I cannot activate the Peacock Premium which is part of my plan for the 2Gig Internet Plan I have. I had this working on the old account. How do we unlink the old account and link the new account??

I get the following message when trying to activate my Peacock Subscription.

Your Xfinity account is already linked to another Peacock account.

Any assistance would be appreciated! Thanks
