I have followed the steps suggested: Went to payment details, selected previous forms of payments, tried to delete the credit card used and I was taken to a screen that said the link could not be found and my credit card still appears. Help!
Same here... someone from Taiwan broke into my account and stole 26€. I tried to delete my credit card info but it seems that option doesn't even exist. Finally I called my bank and blocked my credit card.
you may need to contact customer service, and request for assistance or ask them to delete your credit card details in your account;
