※Notice
You cannot change cards for items that have already been paid for. To remove your card, you need to add another card to continue your subscription. You can't just remove all credit cards from the system while you are still in the subscription period.
To delete all the cards completely, you should cancel your subscription first and delete your account accordingly.
