If you have two active subscriptions under one account, we recommend cancelling one of them. Go to your profile page, choose the “orders & subscriptions” tab on the left-hand side, and choose “subscriptions” from the dropdown menu. On the right-hand side, you’ll see the option to cancel your subscription.
If you need help cancelling a subscription or want to find out if you’re eligible for a refund, contact support@project-syndicate.org.
