THIS CALLER HAS PRETENDED TO BE A LEGITIMATE HCA FACILITY CALLING IN THE COMPANIES BEHALF TO EXTRACT INFORMATIONS FROM THE WORKERS. THE CALLERS NAME WAS "PAUL". WHEN I CALLED BACK I WAS GIVEN A 1-800 NOS. BY AN AUTOMATED MACHINE AND I LEFT A MESSAGE THAT THEY ARE "CROOCKS", AFTER A DAY OR TWO, SOMEONE CALLED MY HOUSE NUMBER BACK AND LEFT A SOUND OF GUNFIRES MESSAGE IN MY ANSWERING MACHINE WITH UNPUBLISHED NOS. THIS IS SCARRY THAT THIS CROCKS WILL JUST TREATHENED HARDWORKING AMERICANS THROUGH BURST SOUND OF GUNFIRES AND KILL US. THIS IS SERIOUS AND I THINK THE FBI SHOULD TRACT THIS MAFIAS BEFORE THEY'LL KILL US. PLS. REPORT THIS TO THE FBI.
