Peacock Activation after moving and transferring service

That's what I'm doing and I get the error noted above as well. I've only ever had one Xfinity or Peacock account, both linked to the same email. From what I've seen, this is happening to many users and has to be manually fixed on your end. 

We can certainly research further into this issue for you, user_68h0qk.  Please send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account. 

To send a Direct Message, please click on the “Direct Message” icon in the top-right corner of the screen, next to the bell icon, click the "New message" (pencil and paper) icon, then type or select "Xfinity Support". Type your message in the text area near the bottom of the window and press Enter to send your message and initiate a live session.
