WHAT IT HANDLES
• Order tracking: looks up the status, courier and tracking number in your Google Sheet
• Returns and refunds: checks each request against your rules (item delivered, within your return window, not a final-sale item) and tells the customer exactly why
• Store questions: answers shipping, payment and policy questions using only the facts you write, and says "I'm not sure" instead of guessing
• Human handoff: passes the customer to your team and logs the request
• Follow-ups: remembers the conversation, so a customer can just reply with their order number
