Customer support is totally useless. I need to TALK TO A REAL PERSON! Email today is impossibly slow. My wife cannot even receive emails on her iphone. She gets a "imap.comcast.net is not responding" message. I cannot even open emails on my new desk top. Comcast does not porvide phone numbers for tech support.
Please see https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email. You can call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/.
I have had multiple troubles with Comcs since December and dbefore the covid nonsense, I was finally shunted tho the Phillipines where they couldn't be understood and knww less thqan noting; I finally stopped keeping a record at 40 hours on the phone with 31 people. Now they just take your money and flip you off. It's impossible and a monoply.
