Incidentally, it may happen that a payment with PayPal isn't accepted (right away). There's not always a clear explanation for this. In case your payment has been declined, you’ll receive a message saying that your Paypal payment has failed.
We advise you to try to complete the payment later, using an alternative internet connection or to choose a different payment method. 
If you're still having trouble finishing the payment, please submit a request via the link underneath this article.
