If after finalizing your order, it remains pending payment, it means that a problem has occurred with your payment method and that it has not been taken into account.
What to do about it? You can place a new order by choosing another payment method. Your order with the status "pending" will not be processed and the amount is not deducted from your bank account.
Our customer service is of course at your disposal if you need help: firstname.lastname@example.org
