If you have received an e-mail informing you that your transaction got cancelled, here are three possible explanations:
the transaction may have been cancelled because it was an authorization request made by the supplier from whom you purchased the product. This request is a one-off debit, made by the merchant to check the validity of your card. Once the request is cancelled, the money will be released on your account. The e-mail you received notifies you to keep you aware that the related funds are back on your account.
The transaction may have been cancelled after a failed authorization request on your card, in which case the supplier would have decided not to charge the card. In this situation, it’s the merchant’s role to cancel the transaction and the money should go back to your account shortly. The e-mail you received notifies that the related funds are back on your account.
You were using a single-use card on an online Marketplace. When several merchants are involved in the payment process and the card has been charged once, it is blocked and other merchants cannot get their share. This is why the full payment is often cancelled.
👉🏻 To avoid this, use a subscription card, intended to be charged as many times as needed within a monthly budget. It must be approved first, but you can pause/delete it at any time after payment to avoid tying up funds unnecessarily on the card.
