Within a reasonable time after receiving a written request and after receiving payment of such reasonable charge as it may require, every insurer and advisory organization shall furnish all pertinent information to any insured affected by a rate, premium, or prospective loss cost made by the insurer or advisory organization. Upon written request, every insurer and advisory organization shall provide within this state reasonable means by which the insured aggrieved by the application of the advisory organization’s or insurer’s rating system may be heard, in person or by an authorized representative, to review the manner in which such rating system has been applied in connection with the insurance afforded the insured. If the insurer or advisory organization fails to act upon such request within thirty days after it is made, the applicant may proceed in the same manner as if the application had been rejected. An insured affected by the action of the insurer or advisory organization on such request may appeal to the director within thirty days after written notice of such action. The director, after a hearing held in accordance with section 44-7532, may affirm the action of the insurer or advisory organization or order remedial action to be undertaken by the insurer or advisory organization.
