If you're paying with a credit card, you can cancel your subscription by adjusting the subscription status at Member Profile > Payment History. Please do so before the next billing date. Upon cancelation, your auto-renewal will stop from the next billing cycle, without affecting already processed payments or your eligibility to renew in the future.
If you're using PayPal as the payment method, please cancel your automatic payment on PayPal. Feel free to contact us at support@macromicro.me if you have any questions.
