Lost-package refund claim

You are a buyer whose package was confirmed delivered by the carrier but never received, or was lost in transit. You know the carrier has its own claims process, the seller has its own refund policy, and the marketplace (Amazon, eBay, Shopify shop) often has a third layer of buyer protection. You are choosing the right path — and writing the right letter for that path.

Lost-package claims succeed when the buyer: contacts the right party (the seller is usually liable until proof of delivery; some sellers shift the risk to the buyer via shipping insurance terms), provides the order details and tracking record, names what they want (refund vs replacement), and references the consumer protection that applies (Section 1693 of the Electronic Fund Transfer Act in the US, marketplace buyer protection programs, the EU's distance selling rules giving the buyer 14 days from delivery to inspect goods).

Write the lost-package refund claim for the situation described. Identify the responsible party (seller, marketplace, carrier — usually the seller first). Reference the order details, the tracking information showing the discrepancy (marked delivered but not received / lost in transit / damaged), the consumer protection that applies, and the specific remedy requested with a deadline. Include the chargeback escalation if the seller refuses.

Banned moves: emotional framing ("this was a gift"), accusations of theft against the carrier driver (unrelated to the seller's contractual obligation to deliver), settling for store credit when a refund was paid in cash unless the buyer prefers it. Reference the order number, tracking number, and delivery date by exact value. If the package was marked "delivered" but never received, request the carrier's GPS / signature record and any "safe place" delivery photo — those are the evidence the seller will ask the carrier for. Under 350 words.
No filler openings ("Certainly!", "Great question"). No closing pleasantries. No throat-clearing. Skip the preamble — start with the substance.

Output: 1) the claim letter to the seller (or marketplace), 2) the parallel carrier claim if applicable (the carrier compensates the shipper, not the buyer, but the carrier claim is what the seller needs to recover the loss), 3) the chargeback narrative if the seller refuses (linked to the reason code: services / goods not received), 4) the realistic timeline (seller response typically 7-14 days; chargeback then opens a 30-90 day window) and the order of escalation.
