In case you see the message saying the credit card was declined, there might be several reasons for that. Based on our experience, in most cases, there are either insufficient funds on the bank account, or your bank is blocking foreign transactions on your bank account.
In both cases, we recommend first to check with your bank - check whether you have sufficient funds on the account, or whether your bank is blocking payments abroad.
If you encounter an issue with the 3D Secure process (3DS), it’s probably your bank blocking payment requests. You therefore need to get in touch with them and ask that they authorise this particular payment.
If none of above is the case, drop us a message, we'll have a look ;-)
