PDF Guru Charged Me Without My Consent for a Subscription

I used the PDF Guru website only once for a single service, and at that time it charged me 0.99. I agreed to this amount because I believed it was a one-time, limited use. However, without my consent, the company later withdrew 249.99 from my card. This charge happened early in the morning while I was asleep, and I never agreed to any recurring subscription or automatic renewal. I want this unauthorized subscription to be canceled immediately and the full 249.99 refunded to my account. Taking money without the user’s permission feels deceptive and unacceptable, especially when it happens quietly overnight. No company should charge such a large sum without clearly informing the customer or obtaining proper consent. I demand that PDF Guru promptly process my refund and permanently cancel any subscription linked to my account. This matter needs to be resolved urgently.
