they said they were irs.  I think it was some FBI bs.

It was neither the IRS nor the FBI.  It was a foreign criminal scammer trying to separate you from your money.

Btw... why on earth would you think the FBI was calling you?

Irs scam call.. Automated message, final notice, lawsuit, call, blah blah blah. Caller id said Santa Cruz, CA.

The IRS will send a letter in the mail if anybody is stupid enough to reply to these things they should have their head examined

IRS would never call, they will send an agent to your door if needed.  So, the moment I heard the message I knew it's a scam.  I was just playing with them, and called back.  A woman with an Indian accent picked up and claimed she was IRS!  Wrong country, Hello?
