Confusion and Lack of Confirmation

This morning I woke up and found out that there was a "pending" charge of about $500 from NCL. 15 minutes on hold later than morning, and I found out that this was a temporary charge that was applied on the last day of the cruise before our bill was settled, and it takes 72 hours for it to disappear. I'm glad we applied it to the credit card and not the checking account, else there'd be $500 less to spend while that cleared. As a side-note, the customer service rep wasn't very patient explaining this with me - like he explains it all the time and I should know better or something.

Still no confirmation that the fax was received. Called the representation that I spoke to on Wednesday, left a message to call or email me back and confirm receipt of the fax. I don't want to end up two weeks later only to call and find out, "Oh, sir, we never got that". I'll call again early next week.
