Called my cell twice yesterday. Left vague automated messages saying to call back about a problem with my file. I called back and asked what company they were calling from and the lady claimed to be with the "Internal Revenue Service Review Department" and then she attempted to get me to disclose personal information. This is apparently a very popular IRS scam right now where they threaten people with lawsuits over "unpaid taxes" and try to get you to send them money, so please be on the alert!
