This calling started on Wednesday, 10-9-2013.  they called every 30 minutes from 12:30pm through 7:45 pm. They started up again on 10-11-2013 every 15 minutes starting @ 10:13 am.

 I answered once to see who it was because I did not recognize the number and got hung up on.  They call and leave silence on my voicemail for long periods of time.  est. 2 - 3 minutes then hang up.  I've called it and get a message that says press 1 to be placed on our do not call list and press 2 to get a call back.  I've pressed 1 on both days and continue to get calls back.  Some investigation needs to be done.
