Insightway selfcore.me Needs to Refund an Unauthorized Charge

I am writing to complain about a charge made by Insightway selfcore.me. On July 17 I only completed an online IQ test as a one-time test and at no point did I intentionally purchase a subscription or authorize recurring charges. However, today I was charged 46.190,60 to my bank card by Insightway selfcore.me, as shown in the attached payment confirmation, even though I did not request any additional service or subscription. My bank account and card are from Argentina. I request the immediate and full refund of the 46.190,60 that was charged to my card and the definitive cancellation of any subscription or future charges associated with my data, email address or card. I also ask you to send me written confirmation that the refund has been processed and that no new payments will be made without my express and informed consent. I expect this situation to be resolved as soon as possible.
