I use to collect all kinds of debt.  The IRS would send you a  letter first.  Please contact your local FBI office as I have done today.  These people are scamming!

I legit thought this was the IRS, they try calling me but good thing I never actually talk to them.

Scam Recordng - says they are IRS and will file suit.  These scammers should be incarcerated for 50+ years.

I received a pre-recorded call from this number saying they are the IRS and owe them money!  What a scam.  I will call them back later and give them a piece of my mind!

Called and left a partial VM using a machine-generated message. Stated I needed to call this number immediately. Another scam. See notes above from CWG40. Saw the same information about how the IRS operates on the local news. This is definitely a scam.
