Serial cards are valid for 10 months. No returns but can be used by another family member, friend etc.
Cancellation policy: During each serial card, 1 cancellation (but also then at least 24 hours before the start of the class) is free of charge in case of sickness etc. In other cases, we can move the lesson to another time slot to replace the original as soon as possible.
Rescheduling of classes: If you know that you will not be able to attend the class at the agreed time because of work trip etc, I will of course try to reschedule the class to another suitable time. Feel free to ask.
