Interesting. Apparently some heifer named "Rosiland Clancy" makes random phone calls to people, demanding that they pay the "US Treasury Department," which her "collection agency" represents. It's not real. It's just not. These criminals do this a LOT, it appears. Check this...
Why always use the same name? She asked for a "Mr. Munger," so it did sound like a person, calling me specifically, instead of a robo-call.
Anyway, here's the point: if you get a call from "Rosiland Clancy," and she gives you the number
1-888-310-2006, ext 3626
to call back...just don't do it. It's a scam.
