Sometimes, a credit card purchase doesn’t seem quite right. For example, maybe you get charged twice for a concert ticket you buy online. Or perhaps you notice a purchase on your mobile banking app that you know you didn’t make.
When there’s a problem with a purchase or it seems suspicious, you may want to cancel it while the transaction is still pending, before it’s posted to your account. If the timing is right, you may be able to cancel a pending transaction with the merchant without it ever accruing interest. Note that, while other credit card companies may have different policies, Discover® doesn’t allow cardmembers to cancel a pending transaction except in cases of fraud or known errors.
