Same here. They called at 11:10 AM, 16-Aug-2016. I did not pick up. They hung up without leaving a message. I am getting several calls like this on my mobile phone these days.
These people where told they were violating the do not call registry. Woman, Melissa Smith, refused to spell out here name, give the corporate address and told me to go on lined and look them up. She told me I was a threat and hung up.
