6. Before You Start

7. Troubleshooting Order

1. Recheck the current official app or website before following an old screenshot.
2. If the menu name has changed, search inside the service with the core keyword.
3. For verification errors, update the app, clear browser cache, and try another browser.
4. For payment, refund, cancellation, or account deletion, save the completion screen.
5. If support is needed, include the date, payment method, device, and exact error message.

8. Important Notes

Convenience services often change menu names, verification flows, and refund rules. Treat old screenshots as references, not final instructions. For irreversible actions such as cancellation, refund requests, account deletion, or official applications, confirm the current policy before pressing the final button.

9. Frequently Asked Questions

Which should I follow if the app and website show different steps?

Use the current official screen for the service you are logged into. For payments, refunds, and cancellations, also check the latest terms or customer-center notice before final confirmation.

What should I do if verification keeps failing?

Update the app, try a different browser, clear cache, and retry phone or identity verification. If the same error repeats, save the message and contact support with the exact time and device.

What proof should I keep after completing the process?

Keep the confirmation number, completion screen, email, text message, and payment or cancellation record. These records help if you need to prove the request later.

Are older guides still reliable?

They can explain the general idea, but the current official page should be treated as the source of truth. Menu names and policies change, so confirm the latest screen before acting.
