This company has been sending text messages and leaving voice-mail with my family members regarding me. I called today to find out what it is regarding and they're claiming a debt to a company that I do not know. When I asked for more information about the supposed creditor, I was told to Google it. I then asked them to stop calling my family members because it is harassment and I was told that they're not harassing them, that they are listed as references - pretty sure they just Google my last name and started calling people.

They also threatened to garnish my wages, but would provide no validating information.
