I would ignore it. How many people on this post got same phone call same threat? These scam artists spoof their numbers, make all kinds of bogus threats. If you request proof of debt I guarantee you will be told it will be produced in court. Also if you request they provide their physical address they will refuse to do so. If you request they mail you documentation, they will become aggressive and abusive
Got a call earlier today from different Ohio area code. It is a scam! Please block. I personally don't answer calls From numbers I don't recognize. Heaven help those that don't or can't due to no caller ID.
