Two Emails for Peacock - Unable to Access "Free" Peacock

 I am having a problem logging in for the "free" Peacock given with Xfinity.  {It used to work okay until the recent promotion was revised}.  

 In researching this it seems I have two emails associated with this account - how do I get rid of one of them?

 Secondly - I've cleared the subscription cache on my Xfinity cable and still can't login in without it requesting that I choose a paid subscription. I suspect the "two" emails might be the issue.

Thanks!
