Been getting these calls at least 6-10 times A DAY!! Its Charter trying to sell me something. I left them because they were awful!!! I gave them a chance to keep me as a customer and 1 of their own employees told me I should leave if I can get a better deal. Well I could and I did. Called them back at the same number 877-671-5868 and had them remove me from their calling list. Lets see how this works.

This is the third time they have called today and it is 12:28 p.m.  No response when answered, just indicated toll free call on the caller ID.

First time for a call from this number.  I didn't answer and no message was left.  

I don't care who you are....If you are selling something I would never buy from you because of your  way of doing business.  If you are giving something away I DON't want it.  This is. Nothing but disturbing.   Go away!

Frequent Calls from this number. I do not answer. They keep calling

yep, its comcast. just called and got my name off the list, but its going to take 30 days to remove.

I've gotten 4 calls from this number in the last month.  Every I have answered and every time there has been dead air.  I just called back and got Comcast sales and marketing division.  I asked them to put me on the do not call list and they said they would.  Seemed like this was a frequent request.  We'll see if they follow my instructions

get calls from the number at all times of day and night.  when I answer they hang up.

This caller phones my number twice three times every week leaves no message who is calling

Got a call from 1-877-671-5868 twice, did not answer.

They called this afternoon, 3/19/2013.   Very choppy message.  I don't trust telemarketers!

Called, said hello, heard breathing on the other end, and then the call ended.

just called me, no answer when I said hello

Didn't pick up.  They left message of dead air this afternoon.  Could hear that line was waiting for pickup maybe?  I'm not a comcast customer.

I didn't pick up the call. Also I am a comcast customer.  Also got a call from 786-224-6275 just 16 minutes prior.

Answered but dead air on the other end. Hung up after waiting a few seconds for a response.

jsut rang an i answered but nothing

Comcast with some promotional 'opportunities'.

Just got a call. I answer the call but they hung up. It is 2/20/2013 11:47. This is very strange.

I've gotten three calls from this number in a week. I never answer and they never leave a message. I'm also a Comcast customer.

Just called me right now. I said Hello but the line hung up. Weird. Comcast is my cable company so maybe it was them idk

I got the same call, but didn't answer. Thanks for the info, though. I'm a Comcast customer so I guess that explains the call.

Call quality was choppy but caller said she was a Comcast product specialist conducting a survey. Just asked me how often I use their services.

This is a marketing company for Comcast.

877-671-5868 is Comcast calling current customers about other available services that they offer.

No message, no idea who it might be.

No clue and no message left.
Do Not Call List is a joke....
