The information requested in these fields (Paybox billing address, Postal Code, City and Country) is the postal address of the card owner which will be used to make the payment, as it was given to their bank.
If the payment does not work, we invite you to check the following things: that you have not put any special characters in these fields, that you do not have an extension on your web browser that can block 3D Secure ( such as the uMatrix extension). Some banks also require that you have accepted the Secure Pass (double authentication system managed by your bank).
3D Secure DSP2 is a more reliable and secure protocol, now mandatory in Europe, but as a result, it can lead to "refusals" (because it is your bank which will refuse to make the payment) if the information entered does not match not what she expects. Therefore, contact your bank in the event of refusal.
