Can't re-add comcast email account

@user_fhl6kh 

Since yesterday, I haven't been able to access my Comcast email on any of my Apple devices. I was told to delete my account and to re-add it after I changed my password. Now, when I try to re-add my account, the incoming and outgoing mail servers are blank. The Xfinity assistant is useless. It keeps repeating that "users will be upgraded to Yahoo accounts". I can't speak with a person, and it will not give me a different answer regardless of what prompt I enter.
