Caller ID said Mercy Health.  We have had some health issues lately and have received many calls from service groups.  Some have been legit and some not legit.  This one appears to be NOT LEGIT.  I tried to talk with a person and got a recording that said I was the only one "waiting for the conference call".  Then I got "boiler room" noise, like dozens of people working phone calls in the room.  When I said Hello, someone mumbled a couple words that I didn't understand, but no one spoke to me.  Sounded like a Middle Eastern accent, but I cannot be sure.  When I asked why they called me, a recording said I was being dropped from the conference call, and the line went dead.   If legitimate, they were certainly unprofessional.
