Some users report checkout failures even after the payment leaves their bank account, often due to “payment security” or 3D Secure errors at the final step, so the platform rejects the order without showing it in your account. This is a widespread issue seen across multiple cards and methods.
To fix it, try a different card or payment method, make sure your card allows online/3D Secure transactions, and confirm sufficient balance and limit with your bank. Calling your bank to enable online payments and retrying can clear the block.
Also, refresh the app, clear cache/reinstall, or use the web checkout instead of the app, since session or app bugs often cause silent failures.
If the payment still shows deducted, contact your bank to dispute or trace the transaction and ask Trendyol support to manually verify whether the order was created.
If none of the above solutions work, please feel free to share your experience. You can also file a complaint on our website.
