For the time being, it’s impossible to update your payment method during an ongoing subscription. In addition, all refunds can only be authorized to the source of the original payment.
If it’s necessary to change your payment method (for example, your credit card is about to expire), we suggest you cancel your ongoing subscription and purchase a new one. You can do that by contacting our support team at hello@colonbroom.com or using the Submit a request feature under this article. After that, you may repurchase ColonBroom using a different payment method.
