I've always emailed [e-mail] with any issues/changes/etc. with my Comcast. Provide them with with all the account info and a phone number. Someone has always called me back within 24hrs that had the authority to make changes or cancel. Hope that helps.

A few years ago I had an issue with Comcast where they were clearly in the wrong. I sent an email threatening to go public to [e-mail] and someone from their "executive relations team" sorted it out quickly.

Fuck Comcast.
