The commitment includes at least 4 lessons per month that must be paid in advance at the beginning of each month.
If canceled, the lesson has to be postponed and taught before the end of the current month. Otherwise, the lesson is lost.
I have a 48h in advance cancellation policy.
In case of termination of the lessons, please mention it at least two weeks in advance.
If needed, I can provide you invoices (IČ: 02603004).
