Mark - 
When you sign up for Voki Classroom or Voki Presenter, you are asked for a credit card for automated billing.which you can cancel anytime. Any customer who is no longer using the product, that was billed in error, will always have their subscription refunded. 
Sorry about any inconvenience this may have caused.

This feature is coming. We can't do everything at once unfortunately - we are a small team. 
Thank you for your patience!
