Someone from this number keep calling my job. when i call the number back a guy tell me that a lean has been placed on me because i owe money. So i am trying to get information on this person, can someone please help me!

I am getting harassing phone calls from this number too. The man on the phone does not sound like he is from this country. He identifies himself as Officer Hernandez (and he doesn't sound Latin or American) and says that I will be arrested on Monday morning at my work or my home. He is always calling leaving the same message over and over. Please let me know what info anyone might have on this scam of a company and how and who I can report them to.
