DramaBox Subscription Keeps Charging Me and Can't Be Cancelled

I am writing regarding unwanted subscription charges for Dramabox that I have been unable to cancel despite multiple attempts. I use Dramabox on my iPhone, but the subscription does not appear under my Apple or Google subscriptions, and I do not know through which third-party platform I originally signed up. Because of this, I cannot locate any option to cancel the service. On my recent credit card statement, there were four separate Dramabox charges billed directly to my card ending in 0512: $16.19 on 05/21, $16.19 on 05/28, $16.19 on 06/04, and $18.99 on 06/11, for a total of $67.56. These weekly charges are a financial burden for me, and I do not want any discounted offers or alternative plans; I simply want this subscription cancelled immediately. I tried to resolve this first through my credit card company. They could not provide any contact number for Dramabox and therefore could not help me cancel the subscription itself, but they have now blocked further charges from Dramabox as of 07/07/2026. While I appreciate that no more payments will go through, I still urgently need the underlying Dramabox subscription to be fully cancelled, as I have no control over it and cannot find it under any of my visible subscriptions. I kindly request that Dramabox immediately cancels my subscription associated with the card ending in 0512 and confirms in writing that no further charges will be attempted. In addition, I am requesting a full refund of the four recent weekly payments totaling $67.56, as I was not able to find any straightforward way to manage or cancel this subscription. If a full refund is not possible, my absolute priority is that the subscription be fully and permanently cancelled without any further attempts to bill me.
