:Wow, every time I've talked to their customer service about a problem they threatened me by saying how much a service call was if the problem wasn't their equipment, which it was their equipment, or at least the coaxial they installed on a prior occasion.
I'm surprised they didn't charge you for installing an additional outlet
It's not a threat. People get pissed when charges show on their bill that aren't explained in advance. And the install is guaranteed 30 days. After that wiring in or on your house is yours. If it's Comcast's equipment, like you expressed, you have no charge to worry about.
