I was charged on my credit card, but the order was not completed. What do I do?

If your purchase was not completed, but there is a charge on your credit card, don't worry!

This is because the moment you include your card details on the website, the system automatically checks with your operator for the availability of the amount for your reservation.

Here, we call the pre-booking of the amount, but it is not the charge itself! 

Thus, as the purchase was not completed, the amount will automatically be released again in a short period (usually, within 5 days).
