ShortMax Dramas Subscription Cancelled but Weekly Charges Continue

Some time ago I subscribed to the “Dramas” service of Shortmax Innovations, with a weekly payment. Three months ago I cancelled the subscription directly in the app, following the steps indicated there, and since then the membership appears as cancelled in the “Manage membership” section. However, despite this, they keep charging me every week as if the subscription were still active. In the screenshot I attach, it can be clearly seen that the subscription appears as cancelled and with an end date, but the charges continue to appear in my account week after week. I have tried to solve it through the application but I have not managed to stop the automatic charges or receive a refund. I request that my subscription to the Dramas service be completely cancelled, that all undue weekly charges made after the cancellation in the app be refunded, and that a written confirmation be sent to me that no new charges will be made to my account.
