I have looked for how to get comcast to stop using this , we only use our comcast account for internet NOT email and NOT the phone. We have asked your staff not to use it, but to use OUR email, and our phone number. But whenever I log in here there are dozens of emails, most all from comcast / xfinity. Come on just stop.
