Testora IQ Charged My Card Without Consent

I recently used the Testora IQ online IQ test and discovered several unauthorized and confusing charges on my Simplii Financial card ending in 6976. On April 6, I was charged 2.85 and 9.91 CAD, and in addition to these, my bank informed me that there was also a roughly 70 CAD charge from Testora IQ that I did not knowingly authorize. These transactions were brought to my attention when my bank flagged them as potential fraud on my account, and due to this situation I was forced to change my bank card number. I do not understand why these amounts were taken, and I was not clearly informed of any such fees or subscription. I consider these payments unauthorized, and this situation has caused me serious concern about the security and transparency of the service. I request that all charges made by Testora IQ to my card be fully refunded, that any account or subscription linked to my card be immediately cancelled, and that Testora IQ provide a clear written explanation of why these amounts were charged so that I can share it with my bank as part of their fraud investigation. I expect this issue to be resolved promptly and in full.
