Michigan Compiled Laws, Chapter 487. Financial Institutions § 487.2165

Sec. 45. (1) A customer may file a written complaint with the office on a form prescribed by the commissioner regarding a licensee. The customer shall include with the complaint documentary or other evidence of the violation or activities of the licensee. The commissioner shall investigate a complaint filed by a customer under this subsection.

(2) The commissioner may investigate or conduct examinations of a licensee and conduct hearings as the commissioner considers necessary to determine whether a licensee or any other person has violated this act, or whether a licensee has conducted business in a manner that justifies suspension or forfeiture of its authority to engage in the business of providing deferred presentment service transactions in this state.

(3) The commissioner may subpoena witnesses and documents, papers, books, records, and other evidence in any manner over which the commissioner has jurisdiction, control, or supervision. The commissioner may administer oaths to any person whose testimony is required. If a person fails to comply with a subpoena issued by the commissioner or to testify with respect to any matter concerning which the person may be lawfully questioned, the commissioner may petition the circuit court for Ingham county to issue an order requiring the person to attend, give testimony, or produce evidence.
