Unknown caller, No message

Just received call regarding timeshare info.  I hung up as I do not own a timeshare

"Important (recorded) message about your time share.." Hung up since I  don't own a time share

Recorded message about my timeshare. I don't own a timeshare. Caller ID read Austin, IN. Warning: this area of Indiana is known to have a rampant drug problem with heroin and meth. I suspect this is a crime ring trying to scam for money.

I have been on the do not call list for YEARS. How do these people get phone numbers? Did not answer. No message was left on VM. I do not know anyone in Austin, Indiana so did not answer. Blocked caller from calling again.
