Ask the seller a focused question about the conflicting detail. Treat an unanswered question as uncertainty rather than implied confirmation.
Avoid opening unnecessary duplicate requests that could split the conversation. Use precise details about the actual purchase instead of assumptions about the cause.
Compare the checkout entry with the option you intended to choose. Review the product reference alongside its visible option name.
