Call from "IRS" who have a case against me. I am to call (206) 317-1741 for details. Yeah, sure I am.

I was told it's the IRS (they have been trying to get ahold of me) and to get more info on my "case file" I am to call 202-239-5630. Since when do they not have my address?

The call you received is overseas scam.
