866-335-7756

Same here...
Answered- 10sec. Of silence- hung up

i got a silent call from the same number.  when i called back, it said it was comcast trying to call about a promotion.

Thx! Just signed up for Comcast 2 wks ago, this number has been call/hangup/no message once per day since 9/1.  Geesh, another number to add to reject list.

Same here, 10 seconds then disconnect.

I get a call from this number almost DAILY and I answer and the same, after 10 seconds it disconnects.  No one ever says anything.

866-335-7756: This people is calling me daily; I am just ignoring the phone call but is annoying!

Finally answered this number after getting a call at least once a day for a week. It is Comcast with a promotion. Hoping that the calls stop now.

They call at least 3 times a day and never leave a message.
