Last month I suffered the ultimate geek distress — an Internet and cable outage for over a week.
It inspired me to air my frustrations here, and the silver lining of the whole situation is that someone at Comcast saw my post and responded with a tip: if you're ever feeling like you're getting nowhere with the customer service on the phone, you can email the corporate team for assistance.
The corporate email address is We_Can_Help@cable.comcast.com. After my first problem was resolved, I used the corporate email address to get help with something else, and received a prompt reply, as well as a fix to a problem I'd had for a while.
Also, just writing an email definitely beats going through an automated menu for 15 minutes, only to repeat the same information to the customer service rep that you just punched in to four previous menus. Ugh.
