Having an unlisted number means NOTHING.  The calls are made in sequence by the computer.  Every possible number is called.

I have received numerous survey calls at different hours. I would appreciate being taken off their master list.  Thank you.

I called the 1-977-530-9646 telephone number on the website listed in an earlier post and made emphatically clear they are not to call, that I am on a do not call list and that if it happens again, I shall turn them in to the appropriate federal agency. I spoke with an "after hours supervisor."

They said they would remove my number immediately. Time till tell if it works.

The call came from Creative Consumers they are in Houston and was asking if I would like to participate in a survery they would pay me $35.  I told him I was not interested and to remove me from his list. He said ok.

They really are a legit company.  I have done surveys for them several times over the past 6 years.  They only get your number because someone who has done a survery recommended them to call you.
The pay ranges from $20 to $100s depending upon the survey.  I have tasted yogurt, listened to radio stations, and set in on a mock trial.  It depends upon who has hired them and for what survey.  If you will tell them to remove your number they will.  Some of their surveys are gender specific or age specific which is why they will ask for a man or woman.  Some of them are specific as to what type of career you are working in.  They are different every time.  You get paid that day right after you have completed the survey.  No waiting for a check in the mail.
