Recording that says it is IRS and a warrant for debts owed and to call a number back.  No names are mentioned, no way to connect to someone immediately (and scream at them).  Please, please ignore any calls you get from so called IRS.  They do not call - you would get a letter if something was amiss and never a phone call.  If you did get sucked in by one of these calls, contact your local police.

A recorded voice of a man called saying he was a officer of the IRS and there was a search warrant out for me.

Number is now used by air conditioning service center.  SCUMBAGS!
