"Lindsay White" left voice messages claiming to offer a reduced rate to pay back taxes (I have none. The IRS contacts citizens via USPS if taxes are owed). The "agency's" caller ID is 413-390-9331 and voice mail message (Ms. White) asks the potential victim to call her directly at 866-407-4860. She offers removal from the call list by pressing 2 (which I did). However they continues to call under anonymous caller ID. I learned to not call them at all. This tells them you are willing to be responsive.
