I have found that telling the marketing callers to... "Never call this number again or I will contact the state attorney generals office" Be firm but don't yell. Works very well, if they call again, call the attorney generals office and complain telling them the callers name, company, and their phone number. If you are asked to send a letter of complant, send it! This means the company in question is being investigated. Minnesota has strict laws regarding phone marketing, use them to your advantage. The marketing callers must have a list of people that take the time to contact the attorney generals office because we do not get calls any more. Dinner time is nice, we get to talk about our day.
