If you are having issues with the credit card payment on our website, please double check that you have written the card details correctly and that you have sufficient funds in your bank account.
Another reason why your card is not accepted could be a form of fraud protection your bank uses in order to block payments that are made internationally (Skoove is a product of Learnfield GmbH - a German company). You can generally change this setting in your online bank or by contacting your bank.
