It took me a while to find this, but here it is, How to file a complaint about Telemarketing Calls

What the FCC Can Do to Help

While the FCC may not award monetary or other damages, it can issue citations or impose fines against those violating the TCPA or other FCC rules regarding unsolicited telephone marketing calls. If you would like to send the FCC a complaint about suspected violations of the TCPA or of the FCC's rules, you can file it by e-mail (fccinfo at fcc.gov), by the Internet (www.fcc.gov/cgb/complaints.html), by telephone 1-888-CALL-FCC (1-888-225-5322) (voice), 1-888-TELL-FCC (1-888-835-5322) (TTY), or by mail:

Federal Communications Commission
Consumer & Governmental Affairs Bureau
Complaints & Inquiries Division
445 12th Street, SW
Washington, DC 20554

Include the following in your complaint:

• your name, address, and daytime phone number;
• the action you are requesting of the violator;
• the date you requested to be added to the organization’s do-not-call list, and the name of the individual with whom you spoke;
• the home or business telephone number the solicitor gave;
• the name, address, and telephone number of the organization placing the calls; and
• the dates and times you received calls from the organization.
