First call on February 3 and the second one today. I answered and after a moment, Allie introduced herself and wanted to verify my old address, which I refused. She then asked for the last 4 digits of my SSN which I refused of course. I pressed her to reveal the nature of the call and the business she works for. She refused then told me she would update her file before she hung up. If she calls again, I will file a complaint with the Michigan State Police.
