Subscription Cancellation Of SweetMax

I have a subscription issue with the mobile service provider SweetMax regarding a service called “Short movie.” I subscribed around September, and since then I have been unable to find any option to cancel this service in my account or on their platform. Despite looking for a way to stop the service, there is simply no cancellation option available, and the subscription continues to charge me R279,99. I find it unacceptable that a service can be started so easily but cannot be cancelled just as easily. I request that my Short movie subscription with SweetMax be cancelled immediately and that no further R279,99 payments be taken. I also ask for confirmation that the service has been fully terminated so that I am not charged again.
