The Attorney General works to protect consumers and ensure a fair marketplace by enforcing Missouri’s Merchandising Practices Act, as well as other laws. By filing complaints, consumers let the Attorney General’s Office know about unscrupulous businesses and individuals. We rely on consumers to act as our partners in rooting out fraud and helping us bring criminals and scammers to justice.
In addition to filing criminal charges and civil lawsuits, the Attorney General’s Office also mediates complaints between businesses and consumers. Each year, this mediation process results in millions of dollars in restitution for consumers through an exchange of services, fulfillment of promises, and many other ways that resolve many disputes.
Because the Attorney General’s Office brings enforcement actions on behalf of the state, not individual consumers, it is prohibited by law from providing legal advice to you. If you want to preserve any private legal rights you might have, you may wish to contact a private attorney.
