Who called from 2034899048

Claimed I had entered a contest to win a prize and thus they had right to violate do-no-call list. I don't believe that I did.  SCAM ?

keeps calling every 10 minutes and no one is on the line...

Hangup last week and this week.  Blocked.

Some sort of insurance scammer.  Heard a lot of voices in the background, the person on the other end said "Hello?" and when I hello'ed back, there was a pause when I could hear another voice whispering and then the person said "Oh, hello.  This is Insure..." hung up and blocked.

They called and left no voice message.
