After receipt of the advance written notice, the licensee, within five days from the receipt of the notice, may file with the superintendent a written demand for a hearing. Hearings shall promptly be held in the office of the superintendent and a cease and desist order shall not be issued until after the hearing. The licensee shall be entitled to present evidence and the testimony of witnesses at the hearing.
