Many factors result in a payment failure, most of which are due to the risk control policies on the payment bank side. There are a few things could be considered:
1. Be sure that you and your bank authorize the payment. You can contact your issued card bank or company to see if they have blocked the transaction and lift the ban.
2. Make sure your card supports overseas payment and have sufficient fund.
3. Please do not run a VPN when order.
4. Try a different browser.
5. If you have another email, please use another E-mail to check out to see the result.
If it still failed to work, please contact the support team.
