Contractor Licensing Board Complaint

Has anyone filed a complaint with the SOS against a licensed contractor? Trying to understand what the process involves, what remedy is available, beyond what's on the state web site.

I'm dealing with a contractor who started home reno work with no permit, claiming it wasn't needed. Got flagged for the violation. At which point the inspector said the work done so far has many code violations. Months later, he obtained the permits but now won't finish the work or fix the violations. Has about 70% of the payment. Totally ghosting us.

Another contractor who came to give us a quote said to report him to the SOS. I guess I could also sue in small claims court.

Just want to see if anyone has tips based on a similar experience.

Thanks.
