I have started working for a telemarketing company. We are cold calling people who have apparently completed a survey, but literally no person remembers or confirms doing this survey. At the start of our script, we lead people in by saying for taking part in the survey they receive a free $20 gift voucher, ask for their name and say its being sent out. What we dont tell them is that they only actually receive a gift card if they buy our product from us. Something doesnt seem right, is this illegal false advertising?
