If you are interested in changing the credit card details you have provided when you signed up, there are two options available for you:
1. You may complete the Payment Authorization Form attached and send it directly to firstname.lastname@example.org with a request to change your credit card details. This option is not ideal, since providing credit card information over the email is not secure.
2. You may change your credit card details through your personal zone on the company's website.
- Log in to your Online Member Zone. (Forgot your password?)
- Hover over Operations and hover again over Payment-canter. Click on Manage Credit Cards.
- Press click on "Add". Fill in your credit card details.
- Check the "Recurrence" Box and click on "Save".

- Insert your e-mail address
- Insert the amount you would like to pay in US$.
- Choose a credit card out of the credit card's list.
- Click on Submit Payment.
