This number called and left a message on my phone saying that if I don't call them back that a federal agent will be out for me. Who are they???

315-207-4902 is a retarded scambot call using scare tactics. Let it go to answering machine and simply delete the message. Wish there's a way for us to sue the scammer for free as a class action suit.
"Ignoring this will be an intentional 2nd attempt to avoid an initial appearance before a Magistrate Judge... to know your case # & to speak to a Federal Agent, call back on 315 207-4902"

Repeated calls from this number threatening arrest. Stupid scam, extremely irritating. Would join that class action suit if it happened! Don't answer if don't know the number, then delete message.

A new number for the "call or go before a magistrate" SCaM- ID is Oswego, NY.

Caller states they are working for the tax investigation dept of IRS and threatens that the person will be arrested for tax evasion and tax fraud, if they do not return the call by the end of the day.
