Cancel Monthly Payments On Netshort

I am being charged a monthly payment related to Netshort and videos, but this charge does not appear anywhere in my banking app, so I am unable to manage or cancel it. The problem started on October 19. I contacted my bank to cancel this recurring charge, but since the payment does not show up in the app, neither I nor the bank could locate any subscription or standing order to stop. As a result, the amount keeps being charged every month without any option for me to cancel it from the app. I request that the responsible company identify and cancel this monthly charge immediately, stop any future collections, and refund the payments that were taken without a visible or controllable subscription in my banking app. I also ask for written confirmation that the subscription or recurring payment has been fully cancelled.
