According to the CA Department of Consumer Affairs web site, there is a state licensing agency for firearms instructors, the Bureau of Security and Investigative Services (BSIS). In my dealings with the Board for Geology (also under the DCA), they are eager to discipline licensees, as it shows that there is a reason for their agency to even exist. I would recommend that people who have been the victims of such poor training and fraudulent actions file complaints with the BSIS.
Here is a link to the BSIS's site where you can verify the instructor has a license:

I have not reviewed the specific laws and Code of Professional Standards that apply to Firearms Instructors. I do know that other professions have very specific prohibitions regarding giving kickbacks for referrals and for performing substandard work.
I am sure that receiving a number of detailed complaints will get the attention of the agency. They will then do their own investigation and take appropriate disciplinary action.
As a side note, I have seen the same ads in the Turner's store in Kearney Mesa (San Diego). I have serious doubts that anyone that took that class got a CCW from
our Sheriff.
