This number calls me at least 4 times a day and when I answered the first couple times, no one says anything.  Then when I attempted to call it back, it said the number could not be reached.

This number calls me several times a day but when I answer, no one says anything. However, I can hear background movement.

The same as the others above...this person calls me sits on the phone; don't say anything and then when I call back it says the number is not in service

same thing happened to tonite @ 8;50
strange

I get this as an automated recording from Comcast with important information about my account. I'm suspicious this is a scam. I have not called them back. I think this is probably a scam. If Comcast really needs to contact me they can write me. The audio is so bad I have to doubt a real company would leave that poor of quality message.
