- How often
- Every session where anything happens: an order placed, a message sent or received, a window stated.
- How long
- One line.
- What it prevents
- Nothing directly. It is what makes a later dispute winnable.
- If you skip it
- You reconstruct from memory months later, and memory loses to a timestamped record every time.
- How you notice you stopped
- You cannot answer when something happened without opening the platform.
What to write down
- The order reference and the date placed.
- The delivery window, which is the event that makes a dispute appropriate and likely to succeed.
- When you sent a message and when one came back, including when one did not.
- Anything that changed, such as a new window being offered or an apology arriving.
Why the window matters more than anything else
A dispute is decided on a record. Dates, the message thread and whatever evidence exists. Filing before the window closes is the most common self inflicted mistake in this subject, because it is usually dismissed and the dismissal costs credibility on the resubmission that actually mattered.
A message cannot move the window either. Agreeing to wait past it, however politely it was requested, costs you the strongest version of your case.
Where to keep it
The same file as your addresses, decided during the storage task. Not on the platform, because a record you cannot reach during an outage is not a record, and not in a message to yourself on somebody else's service.
