Online Tickets Help:
In most cases, during registration it causes trouble if you use '+' in the telephone number field. In this case the system doesn't accept the registration, please use only numbers there ('00' instead of '+').
Another typical problem is the zip/postal code. Please try to write it rather in the address field. If you still have any problem with the online ticket surface, feel free to write to firstname.lastname@example.org or call one of the following numbers:
00 36 30 533 99 33
