DramaCove Unauthorized Charges After Subscription Cancellation and Refund Request

I subscribed to a service from DRAMACOVE for R$ 20,91 and cancelled it before the next billing date, still in the beginning of October. Even though I cancelled it in time, on 09/10 an amount of more than R$ 100,00 was charged to my card, and on 16/10 another amount of around R$ 100,00 was charged again. These charges appear on my bank statement and I did not authorize or agree to any additional fees beyond the initial R$ 20,91. I consider these repeated charges abusive, as I had already cancelled the subscription, and I feel that the company is improperly taking money from my account. I request the immediate cancellation of any active subscription or plan related to DRAMACOVE and a full refund of all undue amounts charged after my cancellation, including the charges on 09/10 and 16/10. I ask that the company review my case as soon as possible, reverse the charges to my card, and ensure that no further debits are made without my express authorization.
