Who called from 3032425631

didn't answer

Unrecognized number on cell phone, answered, but no response; phone then showed it as a missed call. Strange!

called this number back and it is a phone service for charitable org.

This number has called 2-3 times a day for a couple of days now and every time we answer no one responds, just dead air.  Called  303-242-5631 and get a long winded message about the wonderful job they do for charitys etc....
