   1.3. Tracking shows no updates for 4+ days
      1.3.1. Still within ETA -> Escalate to logistics team for investigation
      1.3.2. Exceeds ETA -> Follow "Package exceeds estimated delivery time" process
   1.4. Failed delivery attempts
      1.4.1. Middle East regions -> Confirm delivery info, request GPS link, register for redelivery
      1.4.2. Other regions -> Confirm delivery info, suggest keeping phone available, provide carrier contact
   1.5. Package returned to sender
      1.5.1. Delivery address matches system -> Prioritize reshipment or offer 100% store credit
      1.5.2. Delivery address incorrect -> Offer 50-100% store credit or resend options

2. Delivery Address
   2.1. change delivery address -> Update address if order not shipped
   2.3. Address verification -> Confirm address details

3. Package Marked as Delivered but Not Received

         3.3.2.3. Order >$200 -> Escalate to team lead

5. Package Awaiting Pickup
   5.1. Verify if customer received pickup notification
   5.2. Provide carrier contact info for pickup details

6. Combined Packages with Missing Items
   6.1. Offer options:
      6.1.1. Arrange reshipment
      6.1.2. Provide 100% store credit (6-month validity)
      6.1.3. If customer rejects both -> Offer 100% cash refund

Note: Special considerations
- Do not offer resend if customer already paid customs duty
- For BNPL payment methods (Klarna/Afterpay), emphasize store credit is not real money
- For orders >$200 with special circumstances, escalate to team lead

Customer: What is status of order 123?
Intent recognition response: ORDER

Agent: Your order 123 is currently in Processing status.

Customer: Can I change order 123 address to Chao yang, beijing?
Intent recognition response: LOGISTICS

Agent: I can update the address if the order hasn't shipped yet. Let me check.

Customer: order 123 is currently in Processing status                                                     
Intent recognition response: ORDER

Agent: Address updated to Chao yang, Beijing.

Customer: and another order 456 showed delievered, but I didn't get it
Intent recognition response: LOGISTICS
Intent recognition response: LOGISTICS

Agent: I'm sorry to hear that. Let's verify if the entire package or items are missing. Can you confirm?

Customer: Intent recognition response: LOGISTICS

Agent: Is the delivery address correct for order 456?

Customer: Yes address is correct
Intent recognition response: LOGISTICS

Agent: Since the address is correct, I'll offer a resend or 100% cash refund.

Bob, since the address is correct, we can resend the order or issue a 100% cash refund. Which do you prefer? 

Customer: I prefer 100% cash refund
Intent recognition response: ORDER

Agent: Refund processed for order 456. Expect it in 3-5 business days.

Customer: OK, thanks
Intent recognition response: ORDER OR LOGISTICS

SINCE THE PROVIDED CUSTOMER QUESTION "OK, THANKS" DOES NOT GIVE ENOUGH CONTEXT TO DETERMINE IF IT IS RELATED TO ORDER ISSUES OR LOGISTICS ISSUES, WE CANNOT DEFINITIVELY CATEGORIZE IT BASED ON THE GIVEN INFORMATION. THE PHRASE COULD BE A RESPONSE TO EITHER TYPE OF ISSUE. THEREFORE, WITHOUT ADDITIONAL CONTEXT FROM THE CONVERSATION, IT IS NOT POSSIBLE TO ACCURATELY ASSIGN A SINGLE INTENT.

HOWEVER, IF FORCED TO CHOOSE BASED ON THE GIVEN INSTRUCTION AND THE LACK OF CONTEXT, I WOULD REFRAIN FROM MAKING AN ASSUMPTION. THE CORRECT APPROACH WOULD BE TO SEEK MORE INFORMATION BEFORE CLASSIFYING THE INTENT.

**ANSWER:**
NOT DETERMINABLE FROM THE GIVEN INFORMATION.

Agent: You're welcome! If you have more questions, feel free to ask.

Customer: What is status of order 123?
Intent recognition response: ORDER

Agent: The status of your order 123 is "Processing". It is being prepared for shipment. Would you like to know the estimated delivery time or make any changes to your order?

Customer: Can I change order 123 address to Chao yang, beijing?
Intent recognition response: LOGISTICS

Agent: To change the delivery address, I need to check if the order has shipped. Currently, it's still "Processing". Let me check with our system.

Order 123 has not been shipped yet, so I can update the delivery address for you. The new address will be Chao yang, Beijing, right?

Customer: YES
Intent recognition response: SINCE THERE'S NO CUSTOMER QUESTION PROVIDED TO ANALYZE, I'LL ASSUME A HYPOTHETICAL SCENARIO BASED ON THE GIVEN CONTEXT.

TO FOLLOW THE INSTRUCTIONS, I'LL DIRECTLY RESPOND WITH THE INTENT KEYWORD BASED ON A GENERIC UNDERSTANDING.

IF THE CUSTOMER IS DISCUSSING ISSUES RELATED TO THEIR ORDER (E.G., STATUS, MODIFICATIONS, PROBLEMS, OR PAYMENT), THE RESPONSE SHOULD BE "ORDER". IF THE DISCUSSION REVOLVES AROUND LOGISTICS (E.G., DELIVERY ADDRESS, SHIPPING METHOD, OR DELIVERY ISSUES), IT SHOULD BE "LOGISTICS".

GIVEN THE LACK OF A SPECIFIC CUSTOMER QUESTION, LET'S HYPOTHETICALLY SAY THE CUSTOMER IS INQUIRING ABOUT SOMETHING RELATED TO THEIR "ORDER STATUS."

ORDER

Agent: The delivery address for order 123 has been updated to Chao yang, Beijing. Is there anything else I can help you with regarding this order?

Customer: and another order 456 showed delivered, but I didn't get it
Intent recognition response: LOGISTICS

Agent: For order 456, I'll check. You mentioned it shows as delivered but you didn't receive it. Can you confirm if the whole package is missing or just some items?

Customer: The whole package is missing.
Intent recognition response: LOGISTICS

Agent: Since order 456 is marked as delivered but not received, I'll follow the decision tree. You mentioned the whole package is missing. Can you confirm if the address on the order is correct?

Customer: Yes the address is correct
Intent recognition response: LOGISTICS

Agent: Since order #456 is marked as delivered but not received and the whole package is missing with a correct address, I'll follow the decision tree. The customer is Bob Wang, a returning customer, with an order value not specified.

To proceed, I'll need to check the order value. Can you tell me the total value of order #456?

Customer: $50.
Intent recognition response: ORDER

Agent: For order #456, value is $50, marked as delivered but not received, and the address is correct. I'll check with our system. Since the order value is less than $100, I'll likely initiate an investigation with the shipping carrier. I'll keep you updated on the status.

Customer: OK Thanks.
