Details

I have a cancellation policy which will change the rate for my lessons.
1. If a student cancels the lesson less then 3 hours before the lesson, he or she has to pay 25% of the lesson.
2. If a student cancels the lesson less then 1 hour before the lesson, he or she has to pay 50% of the lesson.
3. Same police applies if I cancel the lesson - next lesson for students will be with 25 or 50% discount.
