A do not call complaint is a complaint by a consumer that he has received phone calls from a telemarketer even though his phone number is on the National Do Not Call Registry. The registry is a government service that allows consumers to opt out of receiving telemarketing calls.
Users can submit a complaint online if telemarketers call a number that has been on the registry for more than 31 days. Enrolling in the registry is free, and registration is available for landlines and mobile numbers. After registering a phone number, users can verify registration by linking the number with an email address and requesting a confirmation. Consumers can link up to three phone numbers to a single email address. The National Do Not Call Registry is a function of the Federal Trade Commission.
