The National Do Not Call Registry gives you a choice about whether to receive telemarketing calls at home. Most telemarketers should not call your number once it has been on the registry for 31 days. If they do, you can file a complaint with the National Do Not Call Registry at this Website https://www.donotcall.gov. You can register your home or mobile phone for free. You may also register with the Wisconsin Do Not Call registry at https://nocall.wisconsin.gov/web/home.asp.
