I've asked a Comcast employee to help you. You should expect a reply in this thread.
If you don't wish to wait for a reply: 1-800-COMCAST (1-800-266-2278) or 1-800-XFINITY (1-800-934-6489)
soumerai, Let's get that cable raised. I'll reach out to maintenance to have it raised. I just need your full name, address, and phone number via private message so I can get started.
