The VIP Membership is a recurring payment that will renew automatically depending on the plan you have selected (1-Month, 3-Month, 6-Month, 12-month).
This is clearly stated in our Terms of Use (Under the Service section: Toomics - Customer Service ) and our Payment Page (.toomics.com/en/mypage/payment) as follows:
Terms of Use under section Service: "VIP Membership is automatically charged to your Payment Method every month. VIP Membership allows you to view, without limits, the contents designated by us for VIP members. For VIP members, unless you notify us, and follow the process to cancel your membership before your monthly renewal date, you authorize us to charge your monthly membership fee to your Payment Method."
Payment Page: "You also agree that your membership will continue until you choose to cancel it."
Having that said, an automatic recurring payment will be made once every period of time you have purchased for the first time.
Please refer to the date stated on the receipt of the purchase you have made for the first time to find out when the next billing date will take place.
