When I cancelled Comcast I was warned about their practice of continuing to bill. I turned in the remotes, and WiFi equipment and bought my own. When I said I wanted (at their store)to be sure the TV was cancelled they said they couldn't do it and that I had to call Comcast to cancel the TV.
That was the first sign that things could be bad. That is what prompted me to look up their Corporate Offices and send a letter telling them to shut off my TV, no longer charge me for the modem, etc (and attached proof that I returned them) and that I bought my own and I would continue to use their Internet and nothing else. I sent the letter registered and notarized with return receipt required and addressed it to the CEO and VP. I never had a problem after that. Just a suggestion.
