Hello Lisa01
What type of credit card are you using?
Payments by credit card will only take place if your credit card is enrolled for 3-D Secure. “Verified by Visa”, “MasterCard SecureCode”, “American Express SafeKey” and “Diners ProtectBuy” are based on a technology called 3D-Secure. This service ensures that only you may purchase online using your credit card.
Best regards,
Roland
