购买选项取消政策

Cancellation Policy
All our products are non refundable. This means once you have signed up for our courses we are unable to provide refunds.
Subscriptions
When you purchase a subscription to a self learning program, you are able to use it continuously during this period. You will be billed based on the subscription duration and frequency that you select. 
Your payment details will be stored securely and you'll be charged for each of these deliveries, unless you choose to pay in advance.
Some subscriptions may auto-renew at the end of their duration. If you don't want to renew a subscription you can cancel it.
If you want to cancel or change your subscription, you can do it at renewal time. Your order confirmation emails have links to your order. You can manage your subscription from there.
