DramaCove: Unable To Cancel Subscription And Requesting Refund

I purchased a DramaCove subscription through an Instagram ad and have been charged twice, without finding any way to cancel the service. In total, I have been charged BRL 213.11 on my Nubank credit card, in two separate transactions, the first for BRL 107.80 on October 13, 2026 and the second for BRL 105.31 on October 20, 2026. On October 18, 2026 I started trying to cancel this subscription. I checked my Apple subscriptions, but DramaCove was not listed there. I also did not receive or find any confirmation email with information on how to manage or cancel the subscription, nor could I locate a cancellation option on any platform associated with DramaCove. After the second charge on October 20, 2026, I contacted Nubank on October 21, 2026 and was informed that I would need to cancel my card. Even after all these attempts, I still do not have any confirmation that the subscription has been cancelled. I request the immediate cancellation of this subscription, a written confirmation that no further charges will be made, and a full refund of the two amounts already charged to my Nubank credit card.
