How to remove a payment option?

You have posted your credit card number AND the security number in a public forum. Are you insane? I've asked the hosts to remove the image. You probably need to speak to your card issuer, cancel that card and get a new one issued. With the information you posted anyone can make purchases on your card: hopefully it wasn't up long enough for anyone to notice.

You apparently have a problem with your payment method where Apple is concerned. You should contact Apple Support

Is the card being declined? See the Apple Support article(s) below. Link to contact Apple Support in the article. 

Apple ID payment information - If your payment method is declined, or you have a billing issue with a previous purchase in the iTunes Store.    

Possible fixes.   Fix ‘Your Payment Method Was Declined’ Error In App Store

                          Payment method declined in iTunes or the App Store.

STOP POSTING YOUR CREDIT CARD NUMBER. YOU'VE DONE IT TWICE NOW. I'VE ASKED FOR IT TO BE REMOVED AGAIN WHICH THE HOSTS HAVE DONE : I SHAN'T BE ABLE TO DO SO AGAIN AS I'M GOING OFF LINE NOW.

CANCEL YOUR CARD. YOU'VE MADE IT POSSIBLE FOR ANYONE WHO SEES THE POST TO PURCHASE USING YOUR CARD. AND DON'T DO THIS SORT OF THING. NEVER POST PERSONAL INFORMATION IN A PUBLIC FORUM.
