Hint America Inc Subscription Cancellation

For the past three months I have been charged for a subscription by Hint America Inc that I never knowingly signed up for and do not understand. The charge is $29.99 per month, and a total of approximately $90 has been taken from my account via Cash App. Each month I believed I had successfully cancelled, yet the following month the charge appeared again. Most recently, I tried to cancel the subscription online on February 24, but despite this attempt, the payments have continued. I request the immediate cancellation of any subscription or recurring payment linked to my details and a full refund of the approximately $90 that has been taken without my informed consent. I also ask for written confirmation that the subscription has been cancelled and that no further charges will be made.
