The calls are coming from a National Marketing Company in Hoboken New Jersey, from the number 201-448-3973. How do I know? I called the number from my private line. They have a message stating that you can be taken off their "list" if you leave your number. Of course, their message box is full.
For those of you on the Do Not Call Registry, if you continue receiving calls, you can actually sue.
Whenever they call, I tell them I'm on the DNT registry and the first thing they tell me is "it takes 6 months to get out of the database" and that is when I inform THEM that i've been on DNT call YEARS. I then tell them that I will sue if I get one more call. I never hear back from them again. I keep a list of numbers that have called, to cross reference.
Today's call came in on my cell and had I had it on, I would have told them directly the same thing above.
