AI Prompt for Resolving Duplicate Subscription Billing Charges

Objective: Create a reusable AI prompt that walks support agents through a structured process to resolve customer claims of being charged twice for the same subscription, ensuring accurate verification, clear communication, and correct refunds or explanations.

The base prompt is built by mapping the required chain of thought directly into sequential instructions the AI must follow. This keeps responses consistent and reduces errors.

Start with role and context so the AI knows it acts as a billing support specialist.
Insert the customer statement as a variable so the prompt adapts to any similar complaint.
Embed the exact verification sequence as ordered steps the AI must complete before giving an answer.
Add placeholders for company specific details and tone so the same template works across different brands.
Close with output rules that force a clear decision and next action.

Note

Keeping the steps in the same order as the original chain of thought prevents the AI from skipping verification or jumping straight to a refund.
