Received the same phone calls. they are scams & bogus. IRS never leaves messages or computer generated calls. They use old school methods of US Postal service & letters, normally registered letters. They have to, to document their files. Also if they would call they would never give a number like the one they tell you to call in these computerized things. The give 800#s.
WHAT???? Richard webber, you are not real. This is NOT a real call. FYI, organisation is spelled organization. Your sentence makes no sense at all. This is a scam. The IRS contacts you via mail, registered mail and then you work with an attorney!
