Kept calling my daughter's line asking for me.  I called the number back and got an automated message stating "you have reached the investigations department, messages cannot be left at this number".  The call then disconnects.  The message doesn't identify the name of the company which is a major red flag to me.

Callers name John Simmons says he wants my address to drop off documents to me for breach and fraud on a payday loan I supposedly filled paperwork out for.

The same sort of thing happened to me. he was irate and intimidating. Stated I was impeding an investigation. I was going to be charged with a crime.

John Lopez, conducting an investigation into someone named Sean Gaffney, whom I do not know, but was the previous owner of my phone number, judging from the number of calls I got for him when I first acquired this number. Anyway This John Lopez said that I was impeding an investigation and would be charged with obstruction of justice.

Also said his name was lopez, and I returned his call and received the same message you did
