Fraudulent call about IRS and law suit what idiots gave me a number to call was a computer-generated call

I just got a call, should I call? They said it's final notice. But I haven't got any before & can't imagine at all. It made me frustrated.

I called the number and the in the background was so loud that the person on the other end could not hear me . He sounded like he was from India and didn't hear to well I had to repeat what I said a few times. He insisted I owed back taxes of. 8900 dollars. He said of I didn't pay I would be arrested for not paying my back taxes. He said I made an error on my 2009 taxes. I asked why he didn't  notify me by mail and he said he sentient a certified letter 3 times an it was returned. I asked him to send me a copy of the letter and he said couldn't and didn't give a reason. After reviewing my taxes there was mistakes. I hung up on him. I've been considering notifying the FBI.

I was missing a word on one of the sentences . The. Corrected sentence is that there were no mistakes on that years tax return.

IRS scam saying you owe money on back taxes and the IRS is going to sue you. Call the FBI .
