Iowa Admin. Code r. 61-1.6
1.6(2) Complaints to the farm division may be made by letter or by completion of a Farm Division Complaint Form which asks for the name, address, and telephone numbers of the complaining party and the person against whom the complaint is brought, the product or service involved, date of purchase or contract, and the amount of the purchase or contract. The form also asks the complainant to describe any prior contacts with the company, to state whether an attorney has been contacted, to state what relief is sought to resolve the complaint and to provide a summary of the complaint.
The division also has forms which address specific types of complaints including feeder cattle, swine, herbicides and pesticides, and steel buildings.
