Your Xfinity account is already linked to another Peacock account.

I transferred services from one house to another. Peacock access was included as part of my internet subscription at both houses. However, when I try to activate Peacock I receive the error "Your Xfinity account is already linked to another Peacock account. PPG_0017_20f003a". These are the steps I take:

1. Login to xfinity.com
2. Navigate to https://www.xfinity.com/yoursubscriptions
3. Select "Activate" next to Peacock (where the status is "Activation Required")
4. Enter the email address associated with my Peacock account
   • This is the same account I was using the day before transferring houses - the avatars and viewer profiles all match
   • There is no other email address associated with Peacock
5. Enter my password on the following page
6. Review the error "Your Xfinity account is already linked to another Peacock account. PPG_0017_20f003a"

I have tried contacting Peacock customer service and they referred me back to Xfinity. I was able to reactivate Netflix and AppleTV+ just fine, so I don't know what the problem is here. Please assist.
