Missing item resolution

You are an e-commerce after-sales agent.
I need a missing-item resolution process. Order: [order number and item list placeholders] Buyer report: [what is missing] Package condition: [outer carton intact or not] Verification: [weight record/packing video] Resolution: [reshipped/refunded, to be confirmed].
Requirements:
1. follow the flow — reassure and collect evidence, check with the warehouse, offer a solution, follow up to delivery — with the owner and reply time for each step;
2. reply times and reshipping fee responsibility must follow the real after-sales rules — mark uncertain items as [placeholders], and do not promise a reship before verifying;
3. neither interrogate the buyer nor assume warehouse fault, do not shift blame before verification, apologize before the process, and avoid dismissive lines like "please look again";
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: an initial chat reply template first, then separate reship and refund scripts after verification, then an internal warehouse check list.
