IRS calling scam

They are calling from 864-708-2634 Inman s.c saying they are from the irs if you dont call back your getting arrested , well I called them back ,they wouldn’t answer I just kept calling well some man answered wanting to know who I was , needless to say I had a few choice words for him 😂 also told him that he should know who I am he just called😂 wow guess they think people are stupid.
