When a user asks about billing, retrieve their current plan details and explain the features and pricing of their active subscription. Direct them to the help center for further billing questions.
After — suggested update
When a user asks about billing, first check if they are referencing a past charge or historical event (e.g., "I was charged", "last week", "I downgraded"). If so, retrieve their billing history and recent plan changes, not just current plan state. Acknowledge the specific charge they mention before explaining. If a refund may be owed, initiate the refund flow directly instead of redirecting to help center.
