Comcast.net email has disappeared

Help!  My comcast.net email of 23 years has disappeared off of my phone, and I cannot access it on the Xfinity home page or the Xfinity app.  Fortunately

I am still receiving it as my default email on my home computer, but can't take that with me to work or when I travel!  Xfinity has been absolutely no help.  I have

spent hours on chat, on the phone with techs, in the stores, and even had a tech to the house and everyone keeps passing the buck.  Today I was given yet

another phone number to call for help.  We have tried all the usual things, changing passwords, etc.  When I click on check email I am directed to a page that

says "managing and using your Xfinity email".  There is a link to connect.xfinity.com.  When I click on the link, a space to enter my Xfinity ID and password pops up 

and 95% of the time before I can enter anything, the page loops back to the 'managing and using...page".  If I'm really fast and enter my info, an XFINITY CONNECT

box pops up with this message: 'a required service is temporarily unavailable.  Please try again later.  (SRV-0001)'  Does anyone out there no more than Xfinity

about what is going on?  I'm really frustrated with the shoulder shrugs and lack of accountability.
