1. Story and practice background

We create extreme exception situations where the browser closes unexpectedly while the payment window is being sent, or the external financial agency system enters maintenance time and processing is blocked. When users face extreme asset fears such as 'Isn't the money on my card just evaporating and the purchase missing?', we establish a reassurance failure matrix request form that provides a clear message that 'withdrawal and payment did not proceed' and prescribes response procedures.

2. Learning objectives

• It is possible to predict potential anxiety points and errors that users may experience when leaving or closing a window during financial communication.
• By clearly determining the presence or absence of a withdrawal, you can write an error-resolution statement that relieves the user of the fear of double payment.
• The failure matrix can be used to design a consistent financial failure response guide.

3. Codex AI prompt card

Copy and paste the prompt below into the AI question and answer window of Codex Client and receive guidance.

Anticipate situations in which problems may arise during payment, and suggest what guidance should be provided to users. In particular, please return the response statement (Failure Scenarios) containing instructions for preventing double payment when the payment gateway window is closed and maintenance time conflicts.
