Scam. claiming from IRS.

A guy called many times, claiming form IRS, totally a scam.

I received a call from this number stating that they were from the IRS. They claimed that I filed my taxes incorrectly and I was in some type of violation of a Homeland Security IRS Act and were going to arrest me in the next 30-45 minutes. It was a lady with some accent. TOTAL SCAM! Please do NOT pick up or take this seriously! Report this number when they call you to the IRS!!

I received similar call just now from a guy with accent for similar reasons. SCAM !!!
I just don't get what can they gain by this scam ?!

Big time Scam, said from IRS
