Hypic Unauthorized Monthly Renewal and Refund Request

I am writing regarding an unwanted renewal of my Hypic monthly subscription, which is billed through Google Play. Although I did not intend to continue the subscription, it was renewed without my consent yesterday and I was charged 1,700 Sri Lankan Rupees. The renewal took place via my Google Play account, which is registered in Sri Lanka. I did not approve or knowingly confirm this renewal, and I only realized it after seeing the charge. I request that the unwanted monthly renewal be cancelled immediately and that the full amount of 1,700 LKR be refunded to my original payment method. I also ask that any automatic renewal for this subscription be disabled so that similar issues do not occur again.
