After you have shipped

If the instrument has already been handed to the courier:

• keep and monitor the tracking information;
• retain photos and videos of the instrument and packaging;
• keep checking the transaction status through official channels;
• if a dispute arises, respond with documented information rather than speculation.

If a disputed return arrives, carefully document the parcel, its external condition and the opening process.

For suspected fraud, use the official channels of the platform, courier, payment service and, when necessary, the appropriate authorities.
