Lost Access to old Comcast email

Hello,

I was using an email address associated with a past account from an old house I used to live at.  I did not transfer service, just kept my email address.  I have my own Xfinity service now, not associated with my old account.

It's been working for the last 10+ years, but earlier this week my outlook was asking for my password.  Almost like the server wasn't recognizing my password.  So I went to the Xfinity site to try to reset my password, but it asked me to join a chat or call.  I joined the chat, but the rep kept trying to reset my password for my current service email.

Hopefully this makes sense, I am just trying to reset my password and get my email running again.
