Procedure on complaint by insured

Sec. 12. Any insured may, in writing, request his insurer or its rating organization to review the manner in which its filing or the filing made by a rating organization on its behalf has been applied with respect to insurance afforded him. Any such insured aggrieved by the failure or refusal of an insurer or rating organization to make such review and to grant appropriate relief within thirty (30) days after such request is received may file a written complaint and request for a hearing with the commissioner, specifying the grounds relied upon. If the complaint charges a violation of this chapter and the commissioner finds that the complaint was made in good faith and that the complainant would be aggrieved if the violation is proven, he shall hold a hearing upon not less than ten (10) days written notice to the complainant, the insurer, and the related rating organization, if any, stating the grounds of complaint. If after such hearing he finds the complaint justified, he shall order the matter complained of to be corrected within a reasonable time, but not less than twenty (20) days after a copy of his written order has been mailed to or served upon the insurer complained against.
