I received two messages on my voice mail from "Officer Gary Anderson" with the Tax Audit Service (from the Federal Government ) saying that my name (he has my name wrong) was reported and before I am arrested I need to call back this phone number, 517 507 5697 due to a local petition against my name. He has a thick India accent.
Very threatening, Guy named Adam with an Indian Accent, I called the number back to tell him what a #$%^ing $%^ he is for running a scam but there is no answer then goes to a busy signal....I will keep trying to call the [***]!
