Who called from 3057177128

This number has called me 3 times this month and no one talks when i answer...

This number is calling my cell....when I answer they hang up!

The company number (Tele-Response Center) goes to back to a company doing a survey or possible offer regarding Comcast cable service.

This is a call/sales center for Comcast.  They call offering you a 30-day free trial of over 60 spanish channels and if you forget to cancel after the 30 days, you will be billed $5.00/month (more/less).

I have received a call from this number for several days in a row. No one says anything. This is annoying.
