Want Hint App Refund

I am writing regarding an unauthorized subscription charge from Hint that appeared on my government-issued Mastercard in the USA. On 09/02/2026, an amount of $34.99 was charged to my card for a Hint subscription that I never signed up for, never authorized, and have never used. I did not start any free trial or give consent for any recurring payments to Hint. I contacted my card provider about this charge and was informed that, for a refund, I would need to resolve it with Hint directly. However, I have not been able to reach Hint or get any assistance, even though I did not purchase or approve this subscription. I request that this unauthorized subscription be cancelled immediately and that the full amount of $34.99 charged on 09/02/2026 be refunded to my card. I also ask that my details be removed from any recurring billing so that no further charges are made without my explicit consent. I would appreciate your prompt assistance in resolving this matter and confirming the cancellation and refund in writing.
