Called threatening. Left the following message: "Under custody by the local Sheriff Department. There are four serious allegations pressed on your name at this moment. We would request you to get back to us so that we can discuss about this case before taking any legal action against you. The number to reach us is 682-253-7128. I repeat 682-253-7128."
I get these every once in a while. I like to call them back, in which case someone will usually pick up and give you a name and that they are part of the IRS, etc, etc.. It's fun to call them back and tell them they owe you money.
Robot called left voicemail with begining cut off. Threatening jail time if no action is taken
Robocall to voicemail but header cut off. Usual cybernetic vague threats of legal action. Deleted ...
Another one saying they will call the police if you don't pay
