If your transaction is declined by the bank or financial institution:
Ensure that all payment details, including postal code, security code, and expiration date, are entered accurately.
If corrections are needed, visit the Billing details page under Account tab. You may be required to sign in if not already logged in. Alternatively, consider using an alternative payment method.
If all details are accurate, attempt to process your payment again.
If difficulties persist, verify that your chosen payment method supports e-commerce transactions.
