This number has been calling for months to tell my co worker that if he doesn't pay him (he claims to be IRS badge number LC20031) that they will come arrest him.  We reported it to police but are told it happens so often there is nothing that can be done.  As soon as we block the number, they use a different number but keep calling.

We get it to my doc office all the time.  If we block it, they call from a new number-same threats

We get it at my doc office at least 2 times a week, asking for the docs by name.  Horrible!

John Smith Called from 347-416-5159 (supposedly an IRS agent, definitely south-asian) demanded my info and told me that I will be arrested if I hung up. I asked him to hold on and told him that I will confirm his badge number with IRS, he threatened me a few times and hung up on me.

A fellow with East Indian accent asked for my wife by name. I sensed it was one of these frauds. I asked him who is he.
Then he said he is from IRS.  Then I asked him if he is not ashamed of himself trying to cheat people like this , does he any self respect rather than attempt to cheat a stranger. The fellow just hung up
