Refund And Cancel IQScore Subscription

I recently noticed an unauthorized charge of US$14.99 on my Hang Seng Bank card ending with 7372, dated 12/06/2026, made by iqscore.me/aa. The only thing I did on their website was answer the question about “How to improve your IQ and cognitive abilities?” and at no point was it clear to me that I would be charged US$14.99 or that I was subscribing to any paid service. I do not understand why this amount has been charged, I did not knowingly approve any subscription, and I have no clear information about what this payment is for. I also could not find an effective way to contact iqscore.me/aa other than an email address, which makes it difficult to resolve this issue directly with them. I request that this US$14.99 be fully refunded, any subscription or paid service associated with my details on iqscore.me/aa be immediately cancelled, and that any future payments to this merchant be blocked so that similar unauthorized charges do not occur again. I kindly ask that this situation be investigated and resolved as soon as possible.
