Our system uses your billing address as a verification factor when processing a transaction. Please ensure it matches the one linked to your credit card, and that there's sufficient funds in your account. Also double-check the credit card number entered, expiration date and CVV number.
Note that when a transaction gets declined, your bank holds a pending amount. It usually resolves itself within a few days. Please keep an eye on your statement; if the pending transaction still shows after a week, please contact your bank for further assistance. Thank you!
