They are not allowed to call after 9 pm nor are they allowed to call before 8 am. But they are allowed to call 7 days a week. Sad to say, the National Do Not Call Registry does not work. I found if you make a complaint, it goes on deaf ears. Beware, they are generating numbers by computer and calling those also, that affects the cell phones more. They are also gathering information off of Face Book and members friends list. No one is safe.
