Would also suggest that you contact the office.
Was it a pending charge or the actual charge. Always use a credit card, not debit for reservations.
What i noticed is that they only charge you few dollars just to hold the spot and rest of all they ask once you get back from your trip. That what happened at my time. But you should definetly call their number or customer service.
The best way is to call the office. Check their web site for contact info.
