Credit Card Numbers change, expire and can get lost. This can affect your account payments.
Due to added security and additional protection of credit card numbers, we don’t have the ability to see your credit card number.
To update or change your credit card numbers, access the Client Login Area and login your account.
Click on My Details
Then click on the Change Credit Card Number link at the top of the page.
Then enter the Credit Card Details.
Be sure to select the type of credit card you will be using. Visa, Mastercard, American Express
If this is wrong the update process will fail and you will have to start over.
