3. Processing orders: Customer service representatives may take orders or process returns, refunds, or exchanges.

4. Providing technical support: They provide technical assistance to customers who have questions or issues with a company’s products or services.

5. Handling billing inquiries: They help customers with billing inquiries, such as explaining charges on their account, updating payment information, or resolving billing disputes.

6. Tracking customer feedback: They track customer feedback and complaints, and use that information to improve products, services, or the customer experience.
