I have been on the DNC registry for years and this creep has been calling and leaving annoying, whiny, long-winded robo messages on my phone for years. Last year he/they left a call back number. I called to tell them to take me off their list and a miserable woman answered and hung up on me. Somebody PLEASE stop him.
He is still at it. Called me again last night. I found a form on the Massachusetts Do Not Call website. Record the dates, and times he calls. When he calls more than once a year, turn him in.
