Received an automated message stating to be from the IRS regarding a lawsuit. I called the number back and got answering machine. I left message stating that I was returning call. Shortly after leaving a message, I received a call back from a guy claiming to be an officer with the IRS, and that he was returning my call. I told him "no, I'm returning your call, but it was before I looked your number up and found that you're a fraudulent caller." Right after I said that, my phone automatically shut down. BEWARE. Hope this information helps!
