Testora Taking Money Without Consent

I hold a credit card with Garanti Bank and recently discovered that Testora has been withdrawing money from my card without my clear consent and awareness of a recurring subscription. While checking my account activity online, I noticed three separate transactions: on 10 January for ₺1,333.15, on 10 February for ₺1,350.36, and on 10 March for ₺1,364.26. These payments are related to an online intelligence test that I took once, but I was not informed clearly that this would result in an ongoing monthly charge. I did not knowingly approve a continuous subscription or regular debits from my Garanti credit card and became aware of the situation only after reviewing my bank statement online. Until that moment, I had no idea that Testora was collecting money every month. I request that any active subscription or membership with Testora linked to my credit card be immediately cancelled and that all unfairly or unknowingly collected amounts be refunded to my card. I also ask that no further payments be taken from my Garanti card without my explicit and clear consent.
