Closing my comcast.net email account??

I have tried every way possible to keep my email account from closing since it's saying it's inactive.   I have followed the steps to keep this from happening but i keep getting emails saying my email account will close shortly.   I looked everywhere for a number to call to speak with a live person since the phone assistant keeps looping me back around to the same thing and doesn't help.

Please assist.  I have multiple other sign in's that use my comcast.net email as the verified email address.  I do not want to have to change this.
