yesterday, i received a call from this number. since i didn't recognize the number, i let my answering machine pick up the call. here's the message they left me: "This message is meant for <my name>. This is investigation officer Jim Marshall from Internal Revenue Services. This call is regarding the warrant (unclear) against your name and your passport is kept on hold by the US government. Your warrant ID is CM10010. So I want you to call me on urgent basis. The hotline to my division is 202-204-0484. I repeat it is 202-204-0484. Again this is officer Jim Marshall with Internal Revenue Services, Washington DC. Have a good day." i did not return the call until it was well after office hours. it went straight to a mailbox with a nondescript outgoing message (no mention of the IRS). "Jim Marshall" did speak with a distinctly indian accent (i should know, i am indian-american myself). apparently, these scamsters are targeting immigrants. see http://stlouis.bbb.org/article/st-louis-count ... bbb-warns-44018
in order to make sure that this is indeed a hoax and not the result of some mail that i missed, i called the IRS. i've been on hold for over 2 hours.
Have a little fun next time. Tell them you're on the phone with another tech support that says your computer has both the "Andorian", & "Romulan" virus. See what they say. Try not to giggle.
Just got a call from these guys a few minutes ago. The caller said "I assume you've got a computer". Same Indian accent, plus lots of background chatter indicating a phone bank. As scams go, this one is pretty unconvincing.
