Our booking process is completely automatic, and we use the newest technology to offer our clients the highest security possible when doing an online credit card transaction. If your credit card is generating a consistent error, verify the expiration date of your card or contact the card issuer to find out whether your monthly spending limit has not been exceeded. Otherwise, we recommend you to complete the booking using a different credit card or make a bank transfer.
