If you get an error message after filling in your payment details when sending a booking request, it means that your payment wasn't validated and the booking request wasn't sent.
What you need to do in this case is:
1. Verify that you inserted the correct credit/debit card or PayPal details;
2. Clear your cache and cookies (follow our instructions here);
3. Close and re-open your browser.
If none of the above work, it may be due to the fact that your payment method doesn't allow online payments, so we recommend switching to another one.
