If this happens to you, these are the bodies that oversee brokerage firms. Here's an honest look at what each one is for — and its limits.
Financial Industry Regulatory Authority. The body that licenses and polices brokerage firms in the United States, overseen by the SEC. Robinhood Financial is a FINRA member firm (CRD #165998).
When you file a complaint, FINRA forwards it to the firm, and member firms are required to respond to FINRA. The complaint becomes part of the firm's regulatory record.
FINRA investigates rule violations and can discipline firms. It does not act as your personal lawyer and generally will not force a firm to reverse a business decision like an account closure. The value is the record and the required response.
U.S. Securities and Exchange Commission. The federal agency that oversees the securities markets, including FINRA itself.
It accepts investor complaints and tips, and provides investor assistance. Complaints help it spot patterns of misconduct across a firm.
Like FINRA, the SEC enforces the law and pursues patterns of wrongdoing; it usually will not resolve a single private dispute for you directly. But it is the federal agency a member of Congress can ask about on your behalf.
Consumer Financial Protection Bureau. A federal agency for complaints about consumer financial products and services.
It forwards your complaint to the company and the company is expected to respond, typically within a set timeframe. Complaints go into a public database.
It is most clearly suited to banking and consumer-finance products; brokerage disputes may be routed elsewhere, but filing still creates a documented, forwarded record.
If you are stuck with a federal agency (like the SEC), your U.S. Senators and Representative can open "casework" to inquire on your behalf as a constituent. They do not publish personal email addresses — you reach them through their official contact forms, which verify your home address. This is a real, underused channel for residents.
