These people call and if you're assistant answers they don't leave a message because they know you don't want to speak to them. They're hustlers of the lowest variety.
I received 4 calls 12.30.12 at 12am, 2am, 4am, 6am, 8am from Northwestern Mutual - The Russo Group 212-867-8989 . I will call them 12.31.12 and also report to CT+NY State Attorney General for Harassment.
I keep getting calls from this number but they leave no messages. I'm sure they got my number from my resume online, but they keep calling me at times when I'm clearly going to be busy at my current job. Smart.
