877-671-5868

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

No message, no idea who it might be.

This is a marketing company for Comcast.

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.

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.

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

Comcast with some promotional 'opportunities'.

jsut rang an i answered but nothing

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

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.

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.

just called me, no answer when I said hello

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

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

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

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

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

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
