First, an earlier answerer implies that YOU can sue for $11,000 where it is actually the FTC that can bring fines of $11,000 for violations of the DNC regs. On the other hand, 15 USC s. 6104 allows a private person to sue for "actual damages" up to $50,000 for violations of the DNC law, as well as an injunction. Good luck with that.
Second, even if you are NOT registered on the DNC list, any repeated violation of your express wish to not be contacted by telephone, and any call made to a residence using a pre-recorded message (other than emergency) or for any non-exempt commercial purpose is a violation of the Telecommunications Consumer Privacy Act (of 1991). You may sue (in state court) for statutory damages ($500 for each call made within a year of asking them not to call, and attorney costs and court fees) for each call received after you asked to be removed from their calling list. If you show they did it intentionally, the court may triple your damage award.
The caller would have the burden of proving they phoned you with an "exempt, commercial purpose" that did not include unsolicited advertising.
You may file a complaint about TCPA violations with the FCC, not FTC.
Third, as mentioned by others, there are many exceptions to the federal laws and regulations regarding unsolicited calls, so you have a bigger challenge in educating these unwanted callers about violating your rights, regardless of what they may think the DNC pertains to.
