In my opinion, the person making these phone calls is named Michael Debraccio who works at St. Raphael's Hospital in New Have CT. The main hospital number is 203 789 3000. Call Human Resources and report this loser. I doubt he'll do it again since everyone knows who he is. He is an employee there.
This call appeared on our missed call function of our phone. It was listed at Hospital of St. Raphael and when you call the number back there's a recording that states "the number you have dialed is not in service at this time".
