Did you know they have a direct support forum at BroadBandReports.com? I used it a couple days ago and it is useful for smaller issues that you don't want to call in. Must be a subscriber and only you and Comcast can read your posts in the direct forum:

i knew about it, but every single issue i've ever had to call for has needed to be resolved by a service order. its never something technical.

i've had my cable mistakenly disconnected a few times, or a line cut from utility work.

i'd also note the irony of having online support for internet connectivity issues.
