I have recieved several calls on my cell phone with no messages left, and when I tried to call it back, it says that it has been disconnected or not in service.

Called 4 times today (as of 1610). Getting pretty annoying, especially since they don't leave messages. The caller ID says MOA.

This number has been calling my elementary school daughters cell several time daily.  Actually answered it and it disconnected.  When I dial it back I get a recorded message "We are sorry but the number you dialed is not a working number" Say WHAT????

I have been receiving these calls now for several days.  I actually spoke with someone yesterday who asked me about answering four simple questions regarding the presidential election and flat out told him NO.  I did politely ask him to remove me from their calling list as I had no intention of participating in any political research ever.  That particular call showed up on my caller ID as American for UT.  

Today I received a call from the same number when I was not home.  This time the caller ID said unknown name.  Of course when I called it back I got the same message as others did saying that "the number you dialed . . ."  I just called it again and now I have a busy signal.  Go figure.

I've received two calls from 801-216-3750 today. No message.
