Unable To Cancel FlickReels Subscription!

I am using the Flick Reels app on my iPhone 15 and I have been charged for a subscription that I cannot cancel. For the past two weeks, Flick Reels has been taking 19.99 USD from my bank card, but the subscription is not showing anywhere in my Apple subscription settings and there is no option to cancel it inside the app. Since the charge appears on my bank card and not as an Apple subscription, I cannot manage or stop it through Apple. At the same time, Flick Reels does not provide any visible support link or contact channel in the app, so I have no direct way to reach the company to stop the subscription or ask for help. I request the immediate cancellation of my Flick Reels subscription and confirmation that no further payments will be taken from my bank card. I also ask for your assistance in providing a clear cancellation method and support contact so that users are not charged for a service they cannot control or cancel.
