Cannot Get Any Emails from Comcast Address [Edited]

@Beck_733 

Yahoo would not take my  email address and wanted me to sign in with a google account.  I did, stupid of me. Now I cannot get any of my emails from my Comcast address and they are very important.

[Title edited to remove personal information - email address]

Can you explain a bit more about why Yahoo would not take your email address?  Did you get the invitation to migrate to Yahoo! Mail?  Google should not have been involved at all.

Are you not able to sign in at https://connect.xfinity.com/appsuite with your comcast.net credentials? or at https://mail.yahoo.com or https://login.yahoo.com ? 

@Beck_733 It looks like @Again has asked the same questions we would ask to get the bigger picture and determine the best options to troubleshoot. Can you clarify the requested items so we can better assist you please?
