Cancel IQScore Subscription and Get Refund

I am writing to report an unauthorized charge made by IQScore on my credit card and to request a solution. On 13/08/2026 the amount of R$ 74,77 was debited to my card through IQSCORE.ME/BILL, even though I had only used the service once in the past and did not authorize any recurring or new payments after that first use. After noticing the debit, I contacted my bank to request a reversal of the transaction, but the bank did not refund the amount and the charge remains on my statement. I request the immediate cancellation of any current or future charges related to IQScore on my card, as well as a full refund of the R$ 74,77 charged on 13/08/2026, since I did not authorize this new debit and have not used the service again. I kindly ask that this situation be analyzed and resolved as soon as possible.
