This number called me a few times, about 2 weeks ago. I never answered, and no message was ever left. I haven't gotten another call from that number. I just switched to Charter so it makes sense this number is calling me based on the poster above. At least I know so I can have some fun with them if they call again.
I just upgraded my charter service to premium HD digital cable on May 6th; This number has called twice a day for the past 2 or 3 days and leaves no message. Again, just one more instance to support the above poster's statement regarding shilling.
