After months of hit-n-miss being able to access my Comcast email.. I switched to gmail. I didn't really want to, I've had an @Comcast email for about as long as I can remember.
Tried a chat...guy in India was able to "refresh" or something and get me into my account, but the next day it was the same old sh!t.
I also REALLY love it when I get a yellow prompt at the top of the email page (every GD time) saying; "a web page is slowing down your browser, what would you like to do?"... Xfinity was always the ONLY site I had open... AND the only website I was sending money to every month.
Gmail rulz. Wish I'd tried it sooner
