I get calls from bristol windows in lincoln ne and when i say im on the do not call list they tell me its just a survey, its illegal, one of the phone numbers is 402-438-8815. I have reported to bbb, attorney general. They have called family and friends and say same thing. Trying to get around the dnc but its not legal. How is it a survey when they try to sell me windows on the same phone call that was a survey. Please follow the law
