Ho cercato, dei effettuare un pagamento, con postepay, ma la transazione non avviene con successo.
Sulla mia casella di posta "cercano di spiegarmi il perché":

We could not process your order because your credit card was declined by the bank. Please read on for solutions to this situation.
Note: For the duration of this email, the term 'bank' will refer to either the bank through which you have obtained your debit card or the credit card company that has issued your credit card, for example, Citibank Visa.

How Can This Happen?
Once your order has been transmitted to us, we send your order details to your bank, who will attempt to authorize the charge (Please note that a credit card and a debit card are treated IDENTICALLY in terms of how they are processed. There is no need to explicitly indicate that a card is a debit card or a credit card).

In this case, your bank has issued a 'Declined' statement. There are several situations in which this may occur:

-It may be that your bank is not allowing your account to be charged for Internet transactions. You may have in fact purchased on the Internet in the past but the vendor may not have an official Internet credit card merchant account, as we do, so your bank was unaware it was an Internet purchase. Please check with your bank concerning this recent order, stating that it is an Internet transaction.

Credo di aver riempito correttamente tutti i campi richiesti, sulla carta è presente una cifra maggiore di quella che dovrei spendere (ho fatto subito il saldo per
controllare). L'unico dubbio è sul campo dove viene indicato l'istituto di credito
che la emette. La prima volta ho scritto Visa electron, poi Banco Posta, la terza
e ultima Poste Italiane (non sapevo più cosa inventarmi). L'esito è stato sempre
lo stesso.
Sapreste darmi un aiutino in merito? Grazie
