You do understand that the list does not delete your number from a database.  It is just a list of numbers.  Legitimate companies look at the list and do not call you.  If you have done business with any companies before you added your number to the list can still call you.  Surveys, political calls, and charities are exempted from the list.  Scammers do not care about the list, but they are breaking the law in the first place.

I was not just replying to this number.  I also just received a call from this number.  No message was left on the answering machine.
