Who called from 7184509205

I got two phone calls, but no voice mails from this number this evening, phoned at 6:45 pm and 7:39 pm.  Folks who do not leave voice mails are deemed suspicious to me.  I assume this is a call bot.

Called at 5:39am and did not leave a message. I was frantic thinking it was family.

Called twice within 1 minute.  Left no message.

Also called me twice and did not leave a message. Tried calling the number today with a different line and the phone number is not in service.

Called at 5:43 this morning. By the time I got to the phone the call had ended. A call this time in the morning is always alarming. These s.o.bs can care less about time zones. And, by the way, the Do-Not-Call service is totally useless.
