Here are five different most common reasons why the payment is declined/rejected:

• when there has been a chargeback for your account and/or credit card in the past, you can’t use this payment option any longer
• you only have three trials to enter the right data
• there is a 48 hour limit for payment through credit card or direct debit
• insufficient balance in the card
• some cards are not accepted by the credit card company, so please try one of the other offered options
