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.
this is a real call
We never send a phone call or send a message that is not have a federal organisation work we have to send you the documents to twice until you cannot see until those not delivered to you then after we can make a phone call.
Got a call that this is my final notice...from IRS...this is the second call within an hour or less...I just hung up. I know IRS would not call me about anything.
