The number leads back to something called predicto.com. I called both predicto and heycosmo and told them they contacted an secure internal government mobile phone and they were kind of scared when i threatened legal action.
HelloCosmo.com, reported them on national do not call registry ( https://www.donotcall.gov/complaint/complaintcheck.aspx )after receiving an unsolicited call this morning around 11am (i.e. - I have not entered in phone number or granted approval for calls to be made to my cellphone). Very ticked off about this.
