How can I describe the timing of an order issue accurately?
Check whether a displayed status includes its own update time. Check whether automated messages arrived later than the underlying action.

What should I do if the product seems different from its description?
Check whether a required step or included component has been overlooked. Base the report on the documented offer and the actual difference you can describe.
