As opposed to a refund, you might be able to encounter pending transactions. This is an actual cancellation of a charge.

No credit will appear on your banking statement when a pending transaction is issued, because the charge is never completed, and therefore is never debited from your account.

Rest assured, no charge was taken from your card, and discrepancies should clear up on your bank statement within 48 hours. If you still see a charge on your statement after 48 hours, please contact our customer service.
