Phony IRS call

Left message on my VM saying this was my 'final warning' (NOT - first message) and that I could get my "case number" and talk to a "federal agent" about whatever it was they claim I did.  I received a very similar call about a year ago, threatening arrest, yada yada, and reported it to our attorney general and FCC.  Needless to say, I won't be calling this one back, and will report them again if I get another one.

very similar to the message left above, final warning and threatening call

Got a call from this number to call back and if they do not hear from me my local sheriff's office will be here to aren't me for outstanding charges.

I just recieved that same call! Apparently they also left a v/mail last week.
