ReelMira Charged My Card for a Subscription I Cannot Access

I subscribed to an online service called Reelmira via a Facebook promotion on or around 29/11, expecting to access short dramas through an application. After signing up, I immediately lost the link and realized that there is no actual app to download and no clear way to access any content, even though I had already paid. Despite not being able to use the service at all, my Visa card has been charged. On 29/10 I was charged $9.99, which is approximately R171.00 in South African rand. Today, on 04/11, I have again been charged, this time $24.99, which is R428.59. I have no effective way to log into any account, access the service or manage my subscription. I have tried to find a way to cancel the subscription or contact Reelmira but I have not been able to locate a working app, a proper login page or any clear cancellation option. As a result, I am currently being charged for a service that I cannot access or use in any way. I request that my Reelmira subscription be cancelled immediately and that both payments, the $9.99 (R171.00) and the $24.99 (R428.59), be fully refunded to me. I also request written confirmation that my subscription has been terminated and that no further charges will be made to my account.
