We receive thousands of bookings and usually it all goes well on the technical side. Unfortunately, in your case, there was a problem. Our IT specialists will investigate your case. We suggest to use a desktop computer or phone/tablet with the latest updated browser (Google Chrome, FireFox or Safari). Older browser versions may not work.
Another possible reason for the malfunction could be anti-virus or adblock software that you might use.
If your payment is not successful, you can :
-> try Paypal. Paypal accepts payments from other credit cards as well, you do not need to open an account with Paypal. Paypal refunds are immediately (but limited to 180 days after purchase).
-> call your bank. Sometimes banks block online transactions to South-East Asia. You may ask your bank to enable payments to Thailand, especially if you plan to use your card there in hotels or restaurants.
-> try another credit card or a card from another bank.
If your booking was been created but not paid and it says that seats will be released soon - you still can pay these seats for a little while. Alternatively, you can book them again once they are released. Our system does not allow double payments. You will not be charged twice.
There are other reasons why a booking may not work:
someone was faster and picked the same seat while you were filling in the form.
you tried to pay with Paypal, went away to have a coffee or to find a password, and the Paypal session was already expired when you came back.
your network connection was unstable and the server response broke down.
your booking went well but you made a typo in your email (or our correspondences have been blocked by your mailbox) and our emails did not reach you.
you tried to make a duplicate booking. Our system does not allow you to do the same booking twice for the same passengers.
other rare reasons or maybe magic.
Before you proceed with the payment, please kindly check the terms & conditions and the cancellation rules for your booking. All cancellation rules are sourced from the 6,000+ transport companies that are connected 12Go system.
