IQScore.me Refuses to Stop Unauthorized Weekly Subscription Charges

I recently accessed the website iqscore.me/lm to take what was presented as a simple IQ test. I did not intend to sign up for any weekly paid subscription or recurring service. However, starting on 03/09/2026, my account began to be charged repeatedly without my clear and express authorization. On 03/09 there was a test charge of 1,00 USD (5,39 BRL), and after that weekly charges of 14,99 USD were made on the following dates and approximate amounts in BRL: 06/10 (81,25 BRL), 13/09 (81,10 BRL), 20/09 (81,85 BRL), 27/09 (82,59 BRL), 04/10 (82,89 BRL), 11/10 (79,15 BRL), 18/10 (80,65 BRL) and 25/10 (79,90 BRL), with the last charge on 27/10/2026. I only used the site once for the IQ test and at no time did I agree to these recurring weekly payments. I request the immediate cancellation of any subscription or recurring charge linked to my data on iqscore.me/lm and the full refund of all amounts charged since 03/09/2026, including the test charge of 1,00 USD and all weekly charges of 14,99 USD up to the last one on 27/10/2026. I ask that these unauthorized charges be stopped and that confirmation of the cancellation and refund be sent to me in writing.
