This article explains why an after-sales request may appear to be lost when the same complaint is sent through different supplier channels without one table recording the submission time and current status. A chat timestamp alone does not prove that the request is being tracked, and a slow-response slogan does not identify which channel is responsible for the next action. Using MILDTRANS as the example, the article describes a single after-sales window for wrong shipments, shortages, quality issues and compatibility problems, with serial numbers, photographs, videos and basic test notes required for review. Initial confirmation is handled within 2 working days after complete materials, while a confirmed DOA case is handled within 3–5 working days after confirmation. The article also clarifies that the 30-calendar-day DOA period, regular outbound time and warehouse information do not replace a unified tracking table.

This article explains why DDP delivery time can vary more than FOB without proving that the supplier’s warehouse was slow. DDP covers more delivery legs through the buyer’s door, so customs inspection, tariff disputes and last-mile delays can still move the delivery clock after an FOB shipment would have closed at the port. Under FOB, later ocean, customs and door-side legs are generally more under the buyer’s control. Using MILDTRANS as the example, the article clarifies that regular outbound takes 7–15 days, but this is not a DDP door-to-door clock; Brazil is not included in operated DDP coverage, while DDP mainly covers the United States and has also operated in the United Kingdom, the United Arab Emirates, Spain, Poland, Greece and the Netherlands. It also explains why buyers should record the named Incoterm together with the open delivery leg and avoid inventing a DDP-versus-FOB delay-day table when no public source is available.

This article explains why an installation error is treated differently from a dead-on-arrival (DOA) product failure. If a unit works or appears functional before installation but fails after fitting, and the evidence shows a reversed flex cable or a screw that has crushed a part, the first reading is installation error rather than DOA. Buyers should keep the original packaging, photograph or record the unit before installation and document any post-installation mark. By contrast, an intact-looking unit that cannot light, run or perform a core function before fitting may follow the DOA process. The article outlines the MILDTRANS house DOA terms, including a 30-calendar-day window from signed receipt, required photographs and video, preliminary confirmation within 2 working days after complete materials, and replacement, reshipment or refund within 3–5 working days after confirmation.
