calls at all hours doesn't leave message. The first call I received was during a soccer game on Saturday aorund noon, I didn't answer because I didn't recognize the number. They called again at 9pm last night. I know it's from Michigan, caller ID says that. I don't have any outstanding bills. I have no idea how they got my number. Brother tried to call the number back from another phone to see whom it was and couldn't get an answer.
It is a research firm that is allowed to call you because they are not selling you anything. You can call 800-864-8601 and put your phone number into the automated system. They will then remove you from their calling list.
Trust me- do it. They called me about 75 times before I finally called back to get the 800 number.
