Caller claiming to be from the IRS. In very heavily accented English: "Hi. This call is from IRS, Internal Revenue Service. This message is for you. As soon as you receive this message I need you or your attorney of records to return the call. The issue at hand is extremely time sensitive. My name is Officer XXX XXXX and hotline to my division is 571-298-1271. I repeat, my number is 571-298-1271. Now, don't try to disregard this message and don't return the call. If you don't return the call and if I don't hear from your attorney either the only thing I can do is I wish you a good luck as the situation badly unfolds on you. So give me a call back as soon as you get this message. Thank you."
