This company has been contacting us for months and each time, I have said we are NOT interested and to NOT call again.
So after getting another call last night during dinner, I called the 800 number from their website. It is their Administration Office and I said, "Hello. We would like to be placed on your Do Not Call list - despite having asked a few of your representatives not to call anymore, we continue to receive calls." She politely said, "Thank you. You've reached the Administration Office and I will make sure your number is put on our No Contact List".
