IRS?? Again and again ,bad thing they know the address also,still scam don't call back, but if some one call you ask him for there address so your lawyer can communicate with them,the guy hang up once he hear about the lawyer.
Guy claiming to be doing an IRS investigation, tells you not to contact or use your lawyer or cpa. Threatens that he'll have the cops at your house in a half hour if you don't work with him.
