Q: I paid my fee, but the session was fully booked and I could not join. What happens?
A: Please check our schedule page before you pay. We will notify as soon as possible when the session is full. However, such a problem can happen. You can join another session of the same value or you can request refund through Paypal. If you request refund, Paypal will deduct a fee (normally about 5% - they have a rather complicated fee system - please check before you choose this option).
