Do not register any credit card or payment option on Facebook to purchase ads, boost page or boost post. Once you do, the card is locked in and they will not allow you to remove it or delete like Amazon does until you replace it with another payment option. The hidden agendas of FB is to continue using your card for random purchasing in order to maintain and elevate the increasing number of Likes on your page. In April, they went too far and made an excessive purchase on my card when there was no recurring payment option set up to do so, clearly unauthorized. Watch yourself. Spread the word!!!!
