Your bank might be blocking the transaction. Call your bank's support line and ask them to allow payments to this merchant. Some cards have spending limits or restrictions on online purchases — check your account settings in the banking app. Try switching to a different payment method: if the card doesn't work, use Apple Pay, Google Pay, or another card. Clear your browser cache and cookies, then attempt the payment again. An outdated app version can also cause payment failures — update it through your app store.
Close the app completely and restart your phone. Free up storage space — the app needs at least 500MB to run smoothly. Check for updates in the App Store or Google Play. If the problem persists, uninstall and reinstall the app. Make sure your phone's operating system is up to date. Disable battery-saving mode as it can limit app performance.
Restart your router — unplug it for 30 seconds and plug it back in. Test your internet speed using any online tool. If it's slow, contact your internet provider. Try accessing the website from mobile data instead of Wi-Fi to rule out connection issues. Disable browser extensions temporarily — ad blockers sometimes interfere with website elements. Switch to a different device to see if the problem is device-specific.
Check your spam and promotions folders — automated emails often end up there. Add the sender's email to your contacts and check again in a few minutes. Verify that you entered the correct email address during checkout. Look in your account order history — the order details are stored there even without an email. Contact support through the chat function if the email doesn't arrive within an hour.
