Customer support triage — worked example

The prompt

Classify this support ticket into one of: Billing, Bug, Feature Request, Account Access.
Ticket: "I was charged twice for my subscription this month and can't find a refund option."

Expected result

"Billing — double charge, refund requested. Suggested priority: high."

Why it works

This is a worked example, not a template: a real ticket in, a real classification out, so you can see how the prompt behaves before adapting it to your own data.
