If a customer indicates that their inquiry is Billing, which conversation node should be used to escalate it to a live agent?

To escalate a billing inquiry to a live agent, the most appropriate action is to end the conversation. This typically indicates that the automated system has recognized that the customer's request requires human intervention for resolution. By ending the conversation, the system can transition the customer to a live agent who possesses the necessary knowledge and authority to address billing inquiries effectively.

Ending the conversation in such scenarios helps ensure that the issue is handled promptly and correctly, using the resources available for complex matters that may not be suitable for automated responses. This approach acknowledges that certain inquiries, like billing, often require personalized service, and direct human interaction is essential for satisfactory resolution.

The other options focus on actions that would not effectively direct the customer to a live agent. Calling an action generally refers to executing a predefined function or response without necessarily involving a human agent. Showing a message provides further information but does not facilitate escalation. Going to another topic might redirect the conversation but does not address the billing issue at hand, ultimately not serving the customer's immediate needs.
