Cancel Any Subscription In My Name

I live in Melbourne, Australia and a few months ago I subscribed to Dramanivo through their app. For the last several weeks I have been trying to cancel this subscription, but I can no longer even find the correct app or a clear cancellation option. Despite my ongoing attempts to cancel, Dramanivo continues to deduct money from my account without my authorisation. Most recently, on 13 November 2026, there is a pending charge of USD 24.99 (AUD 36.77) from Dramanivo on my Mastercard ending 3961. I also tried to contact them through one of their apps about cancelling, but I have received no response at all. I want Dramanivo to immediately stop all further charges, cancel any existing subscription in my name, and ensure that no more money is taken from my account without my consent. I request that they confirm the cancellation in writing and assist me in preventing any future unauthorised deductions.
