DramaWave Charging My Card Without Apple Subscription – Refund Request

I am being charged 19.99 USD by a service called DramaWave, even though it does not appear in my Apple subscriptions and is not connected to my email. I use an iPhone and first encountered DramaWave through the Faveboo app. Despite this, the payments are being taken directly from my bank card. So far, I have been charged 19.99 USD on 10 July and again on 17 July, plus additional small international transaction fees, as shown in my bank statement. Since DramaWave is not listed in my Apple subscriptions and I cannot see any linked account in my email, I have no clear way to manage or cancel this subscription from my side. I request that the DramaWave subscription linked to my bank card be immediately cancelled and that no further charges be taken. I also ask for a refund of the payments already collected, including any related transaction fees, and a written confirmation that my subscription has been terminated.
