PSA: Any problems you have with Comcast, you can solve with a sternly worded email to their “executive support” secret email:
Comcast_CustomerSupport@cable.comcast.com
Comcast_ESC@cable.comcast.com
Comcast_CustomerSupport@cable.comcast.com
Comcast_ESC@cable.comcast.com
This is another path to the Executive Escalation team. IME, they respond quickly and get stuff done.
