Robo calls with no one on the line.  I don't have comcast business service or whatever.

The reps, based upon Service Level Agreements, will have to call you if there's any planned outages outside of their monthly maintenance window.  If they try to upsell you during this call, then you can moan and groan all you want.  Unless you cancel your Comcast/Xfinity business class services, you will get these quite often.  

When I asked them on my frequencies, they responded they were upgrading quite a few markets to facilitate the upcoming load requirements of their services.  Do not fret y'all, they are not as big brother as you may think.

If they are calling to offer services, simply make sure you add them to the do not call registry and tell them not to call.  If they do continue to call and you do not have service with Comcast, then get their ID and submit a complaint with FCC.

800 Service

We answered our business phone with business greeting, no answer

It's Comcast Biz Services:  They left msg on voicemail, a robot-female-voice saying maintenance & possible service interruption 11/2/12 between midnight & 5am.

Kiss my a** Comcast.

It's the Comcast customer service for business line...left a message about possible interruptions between 1am-4am due to upgrades and/or maintenance, I can appreciate the heads up!

Comcast Business Services automated reminder call for outages/maintenance work.

Call and hang up...that is all

Sorry Comcast.  The check is in the mail. :)

This is Comcast Business Services - called to say there will be a brief service interruption next day.

It is a call from Comcast Business Network Systems announcing planned outages for your service.

I am continuously receiving phone calls and when I answer, there is no one there.  Never a message.  Expremely annoying and many times I am on a call with my clients.  The call interrupts my conversation and beeps during my call.  Now I have to ask my client to repeat themselves.

If it is Comcast as I see in other notes...leave a darn message!!!!!  So Rude!!!!!!!

keeps calling every day at the same time on my cell phone

Comcast notifying of upcoming maintenance work that causes outage. I am a customer of Comcast. So I guess it is a legitimate call even though I think they could have sent an e-mail instead of calling and playing back a voice recording.

got a call 1x at 3:45PM PST.  message about a rolling blackout and ask me to call back. no name or department name left on message.  did not call back.

No one on the line.  Comes up as "800 Service"

1-800-NUMBERS ARENT FREE -- dont answer it instead return the call.... 1-800-391-3000: it cost them not you.

It is Comcast. I called back and had my numbers removed even though the numbers are on the no-call list.

Interesting.. the 800 391 3000 is a customer service/tech support number. When they called me that asked to speak with business manager.. as if I was a business.

How clever, use their regular working support number as caller ID.. when it seems they are selling from it also.

Shame on them.. kind of makes you suspicious.. when calling customer service for support.  I never received a call from them until I had called them to report a problem.

It mirrors what spammers do on email servers... they give you a link to "unsubscribe" and by doing so you have validated an email address that gets more spam than you ever dreamed of.  Now seems comcast is following  that same practice via telemarketing back to calls made to them for support.  That offends me as it "adds insult to injury" as I called to report a problem.

They called to market to "business" by asking who made decisions for my business.. I am not a business, and told them I am not a business.  Seems a screw loose at Comcast.. telemarketing to a non business number.. or perhaps, they know that use a business ploy as if that circumvents do not call rules.  I am puzzled at their "business" telemarketing effort... wasting time if in earnest as I am not a business.

They may very well be Comcast, however this was definitely an annoying solicitation.  Guy wanted to be transferred to "My IT Department", after which I asked if they were an employee that needed the help desk, to which he replied "No, I want the person in charge of your telecommunication services, which is usually your IT Department."  I indicated our corporate office deals with that, and of course he wanted the phone number, and I told him he could access our website and there was a lovely, comprehensive contact page there just waiting for him.  "Oh, I don't have access to the internet . . . "  Click.  I hung up on him.  I don't have time to deal with this kind of bs.
