When you try to pay the order by your credit card and ended up submitting wrong billing information such as a wrong zip code or a wrong city, even though your card was declined, you can still see that you were charged for that order as a PENDING STATUS on your credit card account. But actually, you weren't charged. That is why it is in PENDING STATUS on your credit card account.
That pending status would disappear from your credit card account in the next business day.
