Supposed IRS Supervisor saying that IRS has filed a lawsuit due to unpaid taxes and an arrest warrant has been issued for non response and payment. That call is being recorded so it can be used in court both to protect us and the IRS. Said that a local IRS office agent left a note on our door on two separate occasions.  They did not send via postal service, because they were afraid it would get into the wrong hands. Said money could not be drawn on our bank account because a lien had been placed against it.  Wanted us to go to local Walmart or CVS and convert cash money into a Moneygram.
