Xfinity account already linked to Peacock

I recently upgraded my Xfinity account that includes Peacock, Hulu, and Disney+ as part of the bundle. When I tried to activate Peacock, it prompted me to input my email. After I typed it in, I got the error "Your Xfinity account is already linked to another Peacock account". I can't seem to fix this issue and would appreciate any help with it. Thank you.
