Wow Taki, they want to charge her for tech support? They probably consider the issue a user problem and not Comcast because of it being related to gaming. She may want to try and call back and (In no way am I condoning a lie) trying to restate the problem without letting them know it's for gaming.
Maybe we can help her out here too...online gaming is my forte.

I run a few gaming PCs on a couple of PCs at my apartment. It's kind of a side hobby of mine.
