The government has just made an important change that makes the registry more effective. You can now report unwanted calls by filing a complaint on the FTC website. The agency has made its complaint form simple, with numerous drop-down menus to help you through the process.
When you file a complaint you will be asked a series of questions detailing the unwanted call. For example, was the call a recorded message or robocall? Did you receive a phone call or a mobile text message?
When you complete the simple process, you'll see a notice that your complaint has been accepted. Do not call complaints will be entered into a secure online database available to civil and criminal law enforcement agencies. While the FTC does not resolve individual consumer problems, your complaint will help the agency investigate the company, and could lead to law enforcement action.
