Check the official instructions
Look for the operator’s accepted documents, name and address matching rules, approved upload channel and support procedure. These are operator-specific requirements, not a universal Casimo checklist.
Record requests and responses
Note the date and exact administrative step requested. Keep your own documents in a secure place; a public report should contain only the minimum non-identifying details needed to describe a delay.
Different evidence, different confidence
An email-verified review is not a verified transaction. A screenshot can support a report but can still be incomplete, altered or missing context.
