FileWorld Refund For Automatic Subscription

I recently used Fileworld’s online tool only once, solely to merge a PDF document, and at no point did I intend to purchase or subscribe to any paid plan. Despite this, on 30/10/2026 I was charged 39,95 € by “Fileworld EU” for a service described as “plan_limited,” and I only discovered this after seeing the debit on my account and the corresponding invoice from HelloSoftware SA issued in my name. I consider this charge to be an unwanted and unauthorized subscription because I did not knowingly agree to recurring or paid services while using the PDF merge tool. I request that Fileworld immediately review this situation, cancel any subscription that may have been created without my clear and informed consent, and issue a full refund of the 39,95 € already charged. I expect this issue to be resolved promptly and in a transparent manner, and I ask you to confirm the cancellation and refund in writing.
