There are a number of changes you can make to your billing information:

• Update existing payment method - Change the name on the card, your billing address, telephone number, and expiration date.
• Replace existing payment method - Use a new or existing payment method in place of the current one. Replacing a payment method automatically switches any services attached to the new method.
• Add payment method (credit/debit) - Add a new card. Note that you'll need to use this option if your issuer sends you a card with a new number and/or card verification value.
• Add payment method (PayPal) - Add a new PayPal account.
• Change payment method - Switch billing for your service from one payment method to another.
• Assign payment method - Assign services to a particular payment method.
• Delete payment method - Remove a credit/debit card or PayPal account from your available options. Note that you cannot delete a payment method tied to an active service; you'll need to change payment method for the service first.
• Assign default billing address - Assign a default billing address to one of your payment methods. 
• List of payment methods - View a list of all payment methods.

Note: Pre-paid cards and gift cards may not pass the AVS (address verification system) check and may also have issues with recurring charges. Pe-paid cards and gift cards may also have issues with refunds. Please use a standard credit/debit card. For PayPal, make sure that your PayPal account is attached to a bank account. If a PayPal account has a balance on it and no bank account attached to it, it may also have issues with recurring charges.
