Who called from 7189894432

i just recieved a call from this number after recieving a call from another random number, im not sure but i bet they're connected but my area code is 916 so this one is obviously out of state for me

I also received a call from this number shortly after another strange number had called. They called twice in a row

I called this number back and its a job finding agentsy i think, but i never gave them my number.

I RECEIVED A CALL FROM THIS NUMBER  TODAY    IN THE AFTERNOON  ON 01/26/12
THEY WANTED TO ASK ME ABOUT A PERSON   I ADVIED THE MAN THAT IT WAS MY PHONE AND I PAY THE BILL AND I DO NOT REPLY TO ANY QUESTIONS  AS I AM RETIRED FROM LAW ENFORCEMENT  AS SOON AS HE HEARD THAT HE SAID   THANK YOU AND HUNG UP
HE WAS TRYING TO GET MY NAME  AND BY USING ANOTHER NAME TO   HE SAID   VERIFY
IF THAT PERSON LIVED  AT THIS PHONE NUMBER I  DID SAY  NO TO THAT  THEN TOLD HIM WOULD NOT GIVE ANY INFORMATION OUT
THANK YOU
DONT  U EITHER
