A consumer reporting agency may charge a reasonable fee, not exceeding five dollars, for each placement or removal of a security freeze for a protected consumer. However, no consumer reporting agency may charge a fee under this section if the protected consumer's representative provides a police report or affidavit of alleged identity fraud against the protected consumer to the consumer reporting agency, or a request for the placement or removal of a security freeze is for a protected consumer who is under the age of sixteen years at the time of the request, and the agency has a consumer report pertaining to the protected consumer. No consumer reporting agency may charge a fee for any other service performed under this chapter.
