How Do I Change My Premium Billing Information?

To change your billing information, please contact the payment processor directly. 

To find your subscription information, navigate to My Profile then select Settings from the dropdown list. On the settings page, select Premium Subscription and you'll be given the information to your subscription, such as the date it was purchased, the status, subscription ID, expiry date and a direct link to the payment processor where you can update your billing information or cancel the subscription.
