Who called from 3852774125

This unknown number called can left a message if I wanted a medical alert system.  How do these people get your number.

I never answer numbers I do not know.  The phone companies should do something about this. They charge people for unlisted numbers, blocking and then they sell this info to the scammers. Who is the real scammers?

Received the same call over the dinner hour.  Caller ID listed "Utah."  Left the medic alert device message.  . . . Now blocked!

Called my cell phone this afternoon and left a voicemail. Some sort of medical alert thing they are ready to ship to me.

"Free" medical alert system message.  Scam.
