Your card
Nothing was charged.
You came back from the payment page without finishing, so no money has moved and no card has been touched. That is all this page means.
This happens
Usually it is not a decision.
A card is declined, a bank asks for a confirmation that does not arrive, a page is closed by accident, or someone simply wants to think about it. None of those need explaining to us.
Swiss and European banks often block a first payment to a new recipient until they hear from you. A second attempt normally works. If it does not, write to info@
