In-transit damages: requirement of unboxing video to proove in-transit damage

To ensure a smooth resolution process for in-transit damage claims, it may be necessary for customers to provide an unboxing video as evidence.

At times, products may unfortunately sustain damage during the transit process. To streamline the resolution process and efficiently address such instances, we kindly request customers to provide an unboxing video as evidence when filing a claim for in-transit damage.

An unboxing video serves as crucial evidence to support the claim, as it allows us to visually assess the condition of the package and its contents upon arrival. It helps establish a clear timeline, providing valuable insights into how the item was packaged, handled, and the extent of the damage incurred during transportation.

When creating the unboxing video, please ensure the following:

1. Start from the initial unboxing: Begin recording the video from the moment you receive the package. Capture the exterior condition of the packaging, highlighting any signs of damage, such as dents, tears, or watermarks.

2. Document the unpacking process: Record the step-by-step process of opening the package, emphasizing the care taken while removing any protective materials or seals. Be sure to capture any visible damage or indications of mishandling.

3. Focus on the product: Provide clear footage of the damaged areas of the product. Zoom in or adjust the camera angle if necessary to capture the full extent of the damage.

4. Preserve the packaging: Retain the original packaging, including any bubble wrap, foam inserts, or other protective materials used during shipping. This helps provide a comprehensive view of how the product was packaged and the level of protection provided.

5. Maintain a continuous recording: Try to maintain an uninterrupted recording throughout the unboxing process to ensure transparency and avoid any doubts regarding the sequence of events.

Once you have the unboxing video ready, you can easily attach it to your claim or provide it to our customer support team as requested. Rest assured, this video will significantly aid us in expediting the assessment of your claim and reaching a fair resolution promptly.

We understand the importance of a smooth and hassle-free resolution process, and we appreciate your cooperation in providing an unboxing video to substantiate your in-transit damage claim. Our aim is to ensure your satisfaction and make the necessary arrangements for a replacement or refund as quickly as possible.
