Appears to be a Phone Phisihing scam involving Michael Advis and others who claim to be government agents of the Legal Affairs Bureau of the US Treasury Department. They claim to have info about pending legal enforcement actions. I have notified the IG of the US Treasury.
I just got a call from that number saying that it was from the IRS & that I owned money from 2007-8 and if I
didn't sent an instant tax payment voucher they would issue a warrant for my arrest. It was pretty scary.
I too, just received a call from this number, when I called back a man by the name of Landon Carter threatened they were going to come and arrest me right now if I did not make payments arrangements immediately!!!l It sounded like there was a bank of operators working in the back ground. Wow, what will they think of next?
