Worked example

Mistake to avoid
Hide keys in support screenshots.
Working checklist
Use a stable reference connecting order, customer, parcel and amount. Date each follow-up and record its reason. Check payment before specifying courier collection. At period end, compare final outcomes and separate ongoing, delivered and returned parcels. Give customers a clear issue-resolution contact without exposing phone numbers or addresses publicly.
Common question
Are statuses always automatic?
Check the update method supported by each courier.
