I would stop trying to convey how bad it is and start saying what you want them to do.

Same here.

Silent tracking in the first week is normal. Scanning happens at hubs, not continuously.

The address matters more than the contents eventually. Changing what you order when the address is flagged changes nothing.

If it came with a repeat slip, the slip beats every database.

Read the methods section. It is the only part that says whether the conclusion is allowed to exist.

I would take the narrow conclusion. Broad ones are more interesting and less true.
