Record consistent observations
Capture the account identifier, count and timestamp before and after the relevant period. Use the same observation method so a reporting change does not become an unexplained difference in the campaign summary.
Consider concurrent activity
Note other campaigns and known account changes that occurred while the order was active. Total growth can include unrelated additions and losses; the visible difference alone cannot assign every movement to one source.
Ask about the service's assessment
Review how the selected listing defines completion and any coverage. Present the order reference and dated evidence to support rather than asserting that a net-count calculation automatically establishes an entitlement to replacement.
Decision checklist
| Decision | What to check |
|---|---|
| Observation | Same account and measurement method |
| Context | Other activity during the window |
| Terms | Completion and replacement definitions |
Worked example
Hypothetically, an account gains 180 net followers during a 200-unit order period. That difference is a useful question, not a complete causal explanation. The buyer checks the service record and concurrent activity before concluding that exactly 20 units were undelivered.
Example figures explain the decision; they are not current prices or promised results.
