cc question.?

Yes. Your payment must be received and posted to your account to be considered ON TIME. Processing time caused by the system doesn't work in your favor.

If you read their rules, you will see a time of day that the payment must be made by to be credited that day. Sounds like you missed it.

Yes you paid late, but you will be fine

Yes, you must have paid after the cut off time because if it shows the transaction will post on the 18th that means you paid on the 18th which is the same as paying one day late.

Paying so late in the day means that the bank will not process your payment until tomorrow. That means that the clock starts on the 18th.

Second, the due date is the date by which they have to receive the money. There is always at least a one day delay, often two or three. This is why you need to pay things one week in advance. So, by paying late in the day, the bank will process your payment on the 18th. Because this is a Friday, this means that Victoria Secret might not get the money until Monday.

Pay earlier in the future.
