Cancel Subscription On iDrama

I live in the USA and about a week ago I tried to start a VIP subscription on iDrama via my Android phone. The payment screen shows a yearly VIP subscription for 129.99 USD in the name of Beth B*** with options such as Google Pay and PayPal, but the subscription does not appear under my Google account subscriptions and I cannot cancel it from there. I am concerned about being charged without having proper control over the subscription and without the ability to cancel it through Google. I have not yet contacted iDrama or Google support because I first want to clearly state the situation here. I request that my iDrama VIP subscription be immediately cancelled, that any current or upcoming charges related to this subscription be fully refunded, and that I receive written confirmation that no further payments will be taken from my account.
