After you buy a subscription on the Artsum Web Store, you have 30 minutes to cancel your purchase before your credit card is charged. The 30-minute cancellation period begins when your credit card is authorized for the purchase in Payments.
Note: If you buy the app a second time, the sale is final and your credit card will be charged.
To cancel a eBook subscription you just bought:
Login into your account.
Select the subscription you wish to cancel.
On the details page, click Cancel Subscription. If you don't see this option, your 30-minute window has expired.
You will receive a confirmation email. You may see a pending charge on your credit card, but it'll disappear.
Refunds: Once a subscription has been purchased, there is no scope of refunds automatically. You will need to email at contact@artsum.in to initiate a refund. The support staff will consider it and if and when they are satisfied with the circumstances of the refund application, they may act on it.
