If you paid via CCBill or Epoch: ensure you're logged in, head to Plans, and at the top, in the 'My Plan' section, you should see a 'cancel subscription' text. Cancelling your subscription will ensure your subscription will not renew at the end of the billing cycle.
If you paid via Epoch you will be redirected to their cancellation page, as we're unable to cancel your subscription directly.
If you're having trouble accessing your account, please reach out to support@ccbill.com or https://www.epoch.com/, depending on the platform you used for purchasing your plan, in order to cancel your subscription.
If you paid via Cryptocurrency: there is nothing to cancel. The payment was one-time and is non-recurring.
