Need Help To Unsubscribe iDrama

I am using the iDrama service with a monthly subscription from the USA. Although I requested cancellation last month, the subscription continues to try to charge my U.S. Bank Visa Debit Card and I am having a hard time unsubscribing. When I enter the app, I cannot clearly see or use any cancellation or unsubscribe option. In my profile it even shows “Membership Expired”, but despite this, transactions for “Hk Good Drama Technology” continue to appear or be attempted on my bank side. I have also seen similar items such as “Stardust TV” and “Shortswave” in my recent transactions list, which I believe are connected to the same subscription or platform. One of the recent transactions for Hk Good Drama Technology is shown as “Declined” on my bank app, but the attempts keep repeating and this is very worrying for me. I tried to cancel from within the application, but since there is no clear unsubscribe button or working cancellation screen, I could not complete the process. I have an iDrama account under the name “kepneer d***” and UID v0017490***, and even though the system shows that my membership has expired, the charging attempts continue, which is inconsistent and makes me feel unsafe using the service. I kindly request that my iDrama subscription be fully and immediately cancelled, that all current and future payment attempts to my card be stopped, and that a written confirmation be sent to me that my account will no longer be billed in any way.
