Need support accessing Peacock Premium

Like many other people in this forum, I am struggling to access the peacock account I should have access to as a diamond member. When I am re-directed to the Peacock website to activate my account, I am given an error saying "Your Xfinity account is already linked to another Peacock account." I have gone through all of the emails in my household, but none of them are linked to xfinity/peacock. I need support in identifying which email is linked to my peacock account, or support in resetting the peacock account my xfinity account is linked to.
