IRS/US Treasury Department scammer

I got a call from 315-373-1582, claiming that someone was filing an issue against me, and they were going to take legal action against me (something like that) if I didn’t call back. I had a bit of fun calling them back using Textnow (I couldn’t get it to work with Google Hangouts, probably because they only will answer if it’s a number). It probably works with FireRTC, but I haven’t tried calling them using that, I might later.

Also, first post, I assume I did everything right, if not, please don't take an instant ban hammer to my account.

Edit: When I was called, a recording said that that was the US Treasury Department, however, when I called back, they answered as the IRS.

It dosnt work

Yeah, I didn’t get another answer after I tried calling again about 5 minutes ago, oh well, it was true before.

(Also, I don't know if I'm doing replies properly).
