Cannot make a payment with a new Card

I understand you're having trouble with a payment for your AWS account. Based on the information you've provided, there are a few things we should consider:

1. Payment Processing Time: After submitting a payment, it can take up to 24 hours for it to be reflected in the AWS Billing and Cost Management console. If you've just made the payment, you may need to wait a bit longer for it to be processed and displayed.

2. Account Verification: Ensure that you're logged into the correct AWS account. If you have multiple accounts, double-check the account ID and invoice details to confirm you're on the right one.

3. Payment Method Verification: Navigate to the Payment preferences page in the AWS Billing console and verify that your new credit card has been successfully added and verified. Sometimes, new payment methods require additional verification steps.

4. Browser Issues: Try clearing your browser's cache and cookies, or use a different browser to see if the payment status updates.

5. Bank Verification: Some banks may require additional verification for online transactions. Contact your bank to ensure there are no issues on their end and that they haven't declined the transaction.

If you've waited 24 hours and still don't see the payment reflected, or if the "Complete payment" option is greyed out, you should contact AWS Support directly. They can help you troubleshoot the issue further and potentially retry the payment on their end.

When contacting AWS Support, be prepared to provide your account ID, the invoice number (if applicable), and details about the payment method you're using. This will help them assist you more effectively.

Remember, for security reasons, AWS Support cannot disable multi-factor authentication (MFA) for credit cards, so if your bank requires MFA, you'll need to work with them to complete the transaction.

If the issue persists, you may need to consider using an alternative payment method or opening a new credit card specifically for AWS payments.
