A transaction may read as "pending" until the merchant confirms the final transaction amount (i.e. settles the transaction). The pending amount is the authorization for the transaction.
In most cases, the transaction will settle in 7 business days. Once it settles, you will see the final amount that was charged to your card in your transaction history.
Please note that business days exclude Saturday and Sunday, so it's possible it will take longer than 7 calendar days before the charge is removed from your card.
Tremendous does not have the ability to remove pending charges from your card. If you have questions about a pending charge, please get in touch with the merchant.
