What form do customers use to report complaints about a product?

Customers use DeCA Form 40-45 to report complaints about a product. This form is specifically designated for customer feedback and complaints regarding products in the Defense Commissary Agency (DeCA) system. It provides a structured way for customers to express concerns, which is essential for ensuring product quality and service improvements. By utilizing this form, DeCA can effectively track and address customer issues, allowing for a more responsive and customer-oriented approach to complaints.

The other forms listed do not serve this specific function within the context of product complaints. Understanding the relevance of the DeCA Form 40-45 helps in grasping the broader process of consumer feedback in the military sales environment.
