I Was Charged by Hint America Without Authorization and Want a Refund

I recently noticed that Hint America has started taking money from my Cash App card without my authorization. On 09/10 there were two separate withdrawals of 0.50, and there is currently a pending charge of 39.99. I have never knowingly used my card for any transaction with this company and I did not give them permission to charge my card. I also have not received any email or notification from Hint America about an order, membership or subscription, even in my spam folder. I consider these payments to be completely unauthorized and I am very concerned about how this company obtained my card details, as I do not use this card for online transactions. I request that all charges, including the pending 39.99 payment, be fully refunded and that any subscription or recurring payment linked to my card be immediately cancelled. I also request that Hint America remove my card information from their systems and confirm in writing that no further charges will be made to my account.
