How to submit a ticket with the local NOC.

Anybody know how to actually submit a ticket with your area's local network engineers? Myself and several of my neighbors who also use Xfinity have our service become completely unusable at peak times, usually between 6PM-10PM.

It's not reduced bandwidth that's the main issue, it's sustained packet loss and a massive increase in the average pingtime. It makes maintaining a connection to anything outside your local network utterly impossible. 

The poor phone support techs are tied to their script, and when that runs out they just try and schedule a field tech, but he's already been out, replaced our equipment and verified everybody's cabling is good to go. I just want to report the issue to someone who actually has the ability to do something, as I'm guessing the problem is on the local headend.

The whole neighborhoods internet is unusable at peak times, and I'd really like to notify the local Comcast/xfinity NOC without having to resort to signing a business class internet contract as I really don't need the extra upload speed. 

If anyone has any ideas for how to notify the correct team of our neighborhood's problems I would appreciate it.
