I keep getting calls from this Colorado number and they never leave a message.  I live in Arkansas.

I get the same call from Denver and I'm in Louisiana - no voice on the other line, and no message.

I just called it back it's Blue cliff college. Just tell tem that u r not interested anymore in their college they will take you off of the list

I'm not interested please stop calling

Caller ID just says Denver, CO and the number 720-977-1630.  They call me at least 5 times a day, never leave a message, and when I answer they just hang up!!  It's infuriating, to say the least!!!  How do I stop them from calling????

This number calls from 9am to 10pm and I don't know who it is

I am getting numerous calls from this number every day.  I don't know who they are and I want it stopped.  I am out of work and don't have time for the additional interruptions.  They never leave a message and it is to the point of harassment

Please stop calling my phone and not leaving a message.
