This number has been calling me repeatedly. So annoying! I finally answered today but it was just silent.

I got a call yesterday 2-24-2015, I answered but was silent. I tried to call back several times but always had a busy tone. Got a call again today  2-25-2015 . I had put it into contact list so I could identify this caller if I got another call.  So I let it ring hoping for voice message. It did not leave one. I called back, got busy tone once again. I think it is a robot/ automated.

I received a hang up call from this nunber

This phone number has been repeatedly calling my cell,  leaving no message or voice mail.  Very annoying!  It is from Utah.

Constant calls from this number - no one on the other end....no message.
