This number 800-622-5250.  I called this number back and they identified themselves as Comcast Outbound Sales Department.  I recently cancelled Comcast and I suspect that they are trying to get my business back.

Just received a call from this number, too.  It might be from Comcast, as the report 11/30/07 states, as I just had a Comcast installation a couple weeks ago...??

I keep getting them too, but not when I am home. And they never leave a message. I called back and got a machine that said it was "Comcast outbound sales". Maybe I should check my bill before I speak, but I'm pretty sure I am not even late.

I too get calls from this number multiple times a day!!!  If I let it go to the answering machine, they hang up.  The number was identified as 1-800-622-5250!  So how do I stop receiving these calls, it is crazy!!!!

My caller ID said I was receiving a call from an "unknown number."  Several of my friends have a blocked phone number and "unknown number" pops up when they call, so my reaction is to answer it. This time the call went to my answering machine. No message was left so I CID the number and 1-800-622-5250 was the "unknown number"    What gives?

Several calls a day. Stops at start of 4th ring.Twice I have answered and no response both times.
