Define one issue
State whether the case concerns a pending payment, verification request, locked account, disputed bonus rule or another event. Separate unrelated problems into linked case notes.
Build the chronology
List dates, amounts, currency, transaction IDs, status changes and support references. Use original timestamps and distinguish what the cashier showed from what support said.
Attach the controlling terms
Save the relevant account, payment or promotion wording and its URL/version. Quote only the clause needed to explain the disagreement.
Request a concrete remedy
Ask for a payment status and deadline, an explanation of a document request, restoration step, fee correction or written final response. Give support a reasonable response window.
Escalate safely
Use the operator’s stated complaint route and named alternative-dispute or regulator path only after verifying that body independently. Never pay an unofficial recovery agent upfront.
