Cancel My DramaCove Subscription ASAP

I am writing regarding three charges of $19.99 each taken by Dramacove from my bank card within a very short period of time. All three payments show the same merchant name and appeared in my banking app on the morning of 6 November (they may have been processed on the evening of 5 November). I only intended to have one active subscription, not three separate charges within roughly two days. I use Dramacove on an Android phone under the email address doraplunk***@gmail.com. When I tried to cancel my subscription, the system would not allow me to proceed, so I have been unable to stop these repeated payments through normal means. I request that the two extra $19.99 charges, which I did not authorize as separate subscriptions, be fully refunded to my card and that my subscription be limited to a single active plan or cancelled altogether according to my preference. I would appreciate your urgent assistance in resolving this overcharging issue.
