Clearview Construction

This company has been doing unsolicited telemarketing for almost 5 years now. We receive sometimes more than 3 calls a month from them. Sometimes we even get 3 calls a week from them. We have asked, demanded to be removed from their list and they still call. What does it take to get removed from a telemarketing list? Isn't the constant harassment of dozens and dozens of calls illegal? We have asked, begged, even yelled at them. They will not stop the calls. Who is responsible for punishing companies for these actions?We will NEVER do business with a company that telemarkets to us!
