PDF Guru Subscription Charged Without Consent – Refund Refused

I am writing regarding an unauthorized subscription and refund issue with PDF Guru. The service started charging a subscription without any clear prior notice or explicit consent on my side, and only after I saw the charge did I realize that a subscription had been created. After noticing this, I immediately contacted your customer service to explain that I had not been properly informed and requested a refund as well as cancellation of the subscription. In the reply from your support representative Tom, I was told that the subscription was cancelled but that the payment could not be refunded. I find it unacceptable that a subscription can be started without clear, transparent notice and then the payment is considered non‑refundable, even after prompt contact with support. I request a full refund of the 49.99 USD that was charged and confirmation that my subscription is fully cancelled so that I will not be charged again in the future.
