I have been getting numerous calls from this, and when I blocked them, other similar numbers for about a week and a half now. They leave a message, that is clearly computerized, but it is halfway through it, before the voicemail pick-ups and starts recording. Now that is a high quality scam right there... The part it does record says, "...nue service, and the hot line to my division is, 202-241-0104, I repeat it's (same) Don't disregard this message, and do return the call, before we take any action against you. Goodbye and take care."
The IRS doesn't CALL you, to tell you you're in trouble. They do things official like, so everything is done through the mail. Plus, they don't tell you to take care. They're pretty much up front with the fact that they're going to screw you, and you aren't going to like it. So this fraudulent call is trying just a bit too hard, and I guess counts on the fact that people are going to be ignorant of how the IRS does things. DON'T FALL FOR IT! If you don't believe me, and other people on here. Call the IRS direct, and tell them you received a call from someone claiming to be them, and are they trying to reach you. Even if they are, it isn't this way. Call the ACTUAL IRS and ask if that is a number they call from. (It isn't)
