also received a call, did not answer, no message left, couldn't find any info on who it is

Why do you call me, not leave a message and not answer when I call back? I have a family member in the hospital and do not need these type of call. Who are you and what do you want?

[***] call every dam day 12:00 or 12:30.  FYI they have multiple phones with extensions 6292 etc.

Hope this helps everyone. This number 720-428-6291 called me in Texas @ 11:10am 10/3/13 and left a msg on my voicemail. They are located in Colorado. I think they are legit because they left a message saying they were from CLEAR VOICE SURVEYS, which I am a member of. Good luck.
