I'm getting this same issue, too. It seems common, yet I've had considerable trouble trying to get to the correct department using the online chat process. Once, I was transferred to three different departments. That's four online representatives all asking me in succession if it's "okay to check your account to see if you're getting the most out of your services" while not actually fixing the issues services. Not to be overly picky, but when the services aren't working, it's hard to see how I'd be getting "the most" out of them. Anyway, I've been given a ticket number and escalated, but haven't heard anything in a couple of days. I'll e-mail in my details.
This is coming on the heels of a weird problem where my prior DVR box would intermittently cease to be a DVR - the icon would disappear, it would stop recording shows, and I wouldn't be able to access recordings, until I called in for a box refresh. I've posted about that on these forums too. Nobody seemed to know how to fix that either, not even the Make It Right department. I hate to say it, but after 15 years as a Comcast TV customer this is going to be the last month of services if we can't get them working right. I really, really don't like spending so much time trying to get something that I pay for to work the way it should.
