Get on the phone with them or chat to an agent.
If you call them, you'll need to get the automated attendant to connect you to a department that handles customer complaints, or service terminations. I can't remember the exact menu number keys, but it's in the phone menu options somewhere. (Or you many need to contact the billing department, although you're obviously upset, so I recommend the former.)
While I don't know the specifics to your case (like the previous balance you seem to owe), I know that Comcast sometimes offers new customers no service charges for (first time?) address changes, so stuff like this can be frustrating and arbitrarily cruel.

My company is doing an upgrade to servers tonight. What is the plan for comcast to protect us from Krack wifi vulnerability?
This is a major Wi-Fi security protocol vulnerability, so Comcast is only responsible if your company's Wi-Fi router access point(s) is being broadcast with equipment that belongs to Comcast or is supposed to be mantained by them (third party vendors). If that's the case, you'll need to wait for a statement. Obviously, any company would be better of using dependable vendors (like Ubiquiti).
Every other internet connected equipment needs to be updated independent of any routers if they are Wi-Fi enabled.

Hi - I am just a regular user and learned of this attack through my employer who has shut down Wi-fi networks temporarily. My question is - My cell phone was connected to my home Wi-Fi last night and at some point Data Roaming was activated. Does that mean that my phone may have been compromised by this hack?
So data roaming is a carrier thing, and it has nothing to do with the vulnerability. (In fact, if you have a generous data plan for your phone, and if you're paranoid, you should turn off Wi-Fi and use that until you're certain your phone has been updated against this new vulnerability.)
As for the vulnerability: It's not the Wi-Fi routers per se that are vulnerable, although internet routers can be vulnerable, but the real threats are the clients that are connected to those Wi-Fi access points. KRACK is a Man In The Middle (MITM) attack, so it basically tricks your iPhone or laptop into connecting to a tampered "clone" of the "real" network this iPhone or laptop is supposed to be connected to. It does so by "cloning" the access point and using the same MAC address as the "real" access point.
The attacker in the above scenario would be able to snoop on any data you send through unprotected websites. Everyone should use a web browser extension that forces HTTPS (HTTPS Everywhere; and for good measure, install any other extensions that enhance privacy). However, there's a really malicious version of this attack that can actually force an unprotected connection on websites that have HTTPS, so that would be a bad scenario.
If you are at real tangible risk, you probably already know it: Government workers, large enterprises, etc.
Residential internet users don't have as much to worry about, unless you're paranoid and have reason to believe you would be a juicy target of this new attack (you would also have to read up on just which devices and operating systems are at worst risk).
If you have an iPhone 5s and above (the models getting updates), you should have nothing to worry about, since Apple will push out an update pretty soon, as is their track record. If you have an Android that isn't a flagship, and that released over 6 months ago, well. . .
This is not the last time such a vulnerability will be discovered. Take a real good look at how quickly an update is pushed out for your electronic Wi-Fi enabled devices. Smartphones, your router, some internet connected toaster you have (I hope those aren't real), and the next time you buy something (say a router or a smartphone), be sure to prioritize the commitment to quick security updates that each company promises (and their proven record of doing so).
*Uh, I should clarify—someone mentioned this above— that there is still no hacking tool available in the wild. This is all proof-of-concept. If hackers manage to create a tool and steal data, that will be reported on the news (or at least on techie sites, depending on the target); for now this hasn't happened. Expect developments on this matter.

(Folks reading this thread, keep in mind that client devices, independent of your Cisco or Netgear router access points, are still vulnerable.)
If you have a Comcast Netgear router, you'll find the latest firmware updates for all of the Netgear models here. Expect Comcast to confirm or clarify which models have to updated, if there haven't been any updates yet.
