Got a very poorly made recorded message saying that this was "officer Lauren Matthews" with the IRS, and that I needed to call 347-853-8699 before action was taken against me.
I just received this same message that the IRS was calling... This is officer Lauren Mathews from the IRS time sensitive issue and that I need to call 1-347-853-8699. This was a computer generated voice. Pretty sure this is a scam.
