Final answer:
Complaints about Med-Services are typically handled by the Customer Service Manager, who is responsible for resolving customer issues and improving service quality.
Step-by-step explanation:
Complaints about Med-Services are primarily the responsibility of the Customer Service Manager. This manager's role is to address customer issues and improve the customer experience. When a complaint is received, the Customer Service Manager will assess the situation, interact with the customer to resolve the complaint, and work towards ensuring better service to prevent future complaints.
However, depending on the nature of the complaint, the Operations Manager, Human Resources Manager, or Quality Assurance Manager could also be involved if the complaint is related to their respective areas of oversight.
