A pending transaction happens when you have used your card at a merchant, and the money has been reserved from your account, but hasn't yet been claimed by the merchant.
It can take 3 to 4 days for the merchant to claim the money. When this happens the transaction changes from pending to complete. If the transaction was canceled, sometimes it takes more time for the funds to be released back into your account. If you want the funds to be released sooner, please contact our support team to see how we can help.
