To ensure your payment is successful, we advise you to manually enter all data fields (payment, billing, etc) and not allow web browsers to auto-fill data when making the payment. Do not use tab or arrow buttons to navigate the page when completing your payment form. If you've already failed a CAPTCHA please clear your cache and cookies and try again with the above method. Or try using a different web browser to try again while being careful to not allow auto-fill.
