Domestika Auto-Renewed My Plus Subscription Without Any Notice

The annual renewal fee for my Plus subscription on Domestika was automatically charged to my credit card on May 28th, without any notification and without my consent. As a result of this transaction, $37.47 was charged to my card.
I received no email, SMS, or in-app notification before the payment, and no clear warning was given that the subscription would be renewed. As soon as I noticed the situation, I contacted Domestika and requested that this charge, made without my permission, be canceled and refunded, but I was told that the Plus subscription fee would not be refunded. Following this, in order to prevent this from happening again, I turned off the auto-renewal feature myself.
I am requesting that this transaction, which took place without my knowledge or consent, be canceled, that the $37.47 Plus subscription fee be refunded to my credit card, and that I be informed in writing regarding this matter.
