Same thing here. No message left when I ignore it. Weird and annoying.

Always asks for Michelle Smith.  No such individual has ever lived here or are related to me.  When I asked they remove my number from their calling list, the female who did not identify herself hung up.

Recieved 3 calls in a row from 1-912-233-9021000  - they left no message.

same thing - called, no message left.  I didnt answer

this caller called before 9am in the morning, asked for someone who did not live here.  My reply was I know that this is a scam call and they should be ashamed of themselves un trying to scam inocent people out of money, and I hung up.  Decided to do a redial to see where this would go.  The Nubmer that showed was1 912 233 9021 00, message I got was 912-233-9021 was no longer in service.  So who knows where this originates from.  Flea bags like this need to be stopped.
