The Michigan Public Service Commission (Commission) will attempt to resolve as an informal complaint any regulated matter brought to its attention by any person not requesting initiation of a contested case proceeding at the Commission. An informal complaint can be sent to the Commission by filling out the form on the Commission's website, calling the Commission's toll-free number (1-800-292-9555), faxing the complaint to 517-241-6272 or mailing a letter to the Commission.

If you are not satisfied with the results of an informal complaint investigation by Commission staff, you may pursue a formal complaint with the Commission. Because the Commission's authority is limited to that provided by statute, a formal complaint can only involve issues that the Commission regulates. The formal complaint involves a formal, trial-like proceeding before an administrative law judge. As a contested case before the Commission, a formal complaint hearing is conducted under administrative hearing rules. You may represent yourself (except in the case of an incorporated business), hire a lawyer, or bring anyone you would like to assist you. A lawyer or lawyers will always represent the company. As the complaining party, you must present information to prove or justify your case at a formal hearing.

Although not required, the Commission encourages customers to pursue an informal complaint prior to filing a formal complaint.
