Unauthorized Payments Made by Hint Without My Knowledge

I would like to report unauthorized charges made by Hintapp.com/us for 29.99 USD to my Česká spořitelna credit card. I noticed the first charge on 28.02.2026, the second on 14.03.2026 and the most recent one yesterday. I am not aware of ever having given my consent for any subscription or service with Hintapp.com/us, and I did not authorize these repeated payments. These debits were made from my Česká spořitelna credit card. I tried to reach Hintapp.com/us about these charges, but they do not respond to me at all. I have not yet contacted Česká spořitelna, because I am first trying to clarify the situation with the merchant. On my bank statement, the transaction shows with ID 0314513062890, fixed reference number 1178 and variable reference number 13032026. I request a full refund of all unauthorized 29.99 USD charges, the immediate cancellation of any subscription or service that may have been created in my name, and written confirmation that all such subscriptions have been permanently canceled and that no further charges will be made to my card.
