Hi there! I understand you're having trouble with paying via Visa card on Ferryhopper for the Sanur to Gili Gede Bali ferry route. Let me help you sort this out.

First, just to clarify:
- Are you seeing an error message when you try to complete the payment?
- Is the issue only with your Visa card or have you tried other cards as well?
- Also, are you booking through the Ferryhopper website or a mobile app on your Windows device?

Meanwhile, here are some steps to try to resolve the payment issue:

1. Check that your Visa card is authorized for international online payments—some cards require this to be enabled by your bank.
2. Clear your browser cache and cookies in WebKit on Windows 10 to ensure no old session data is interfering.
3. Try using incognito mode or another browser if possible, just to rule out browser-specific issues.
4. Ensure your billing address details exactly match what your bank has on file for your Visa card.
5. If the card has a security or 3D secure verification, make sure to complete that process when prompted.
6. Confirm your internet connection is stable and that no VPN or firewall settings might be blocking payment processing.

If none of those work, it could be a temporary issue with the payment gateway or card provider. You might also want to try an alternative payment method supported by Ferryhopper, such as Mastercard or American Express, if available.

Feel free to update me with any error messages or steps you've already tried, and we can dig deeper. If needed, I can also direct you to Ferryhopper's direct support at [email protected].

Are you able to share a bit more about what happens when you attempt the payment?
