Your rights under the TCPA
The Telephone Consumer Protection Act (47 U.S.C. § 227) lets consumers sue over certain prerecorded or autodialed calls made without consent, for $500 per violation, and courts may increase damages up to three times when the violation was willful or knowing.
For telemarketing calls to a number on the National Do Not Call Registry, a private claim generally requires more than one call within 12 months from the same company. Keep a record of dates, times and any company name the caller gave.
