FileWorld Charged Me After Cancellation and Refused My Refund Request

I used FileWorld on or about 07/09/2026 to convert my son’s football highlight video from one file type to MP4. For this, I agreed to and paid a one‑time fee of €0.60 (about $0.60) using my debit card, believing it was a single‑use file transfer service and not an ongoing subscription. Immediately after using the service, I canceled the subscription because I have no further need for FileWorld and did not intend to sign up for any monthly plan. Despite this, today I was alerted by my bank that my account was charged $39.95 under invoice number 1211872. I did not knowingly authorise this additional $39.95 transaction, and I was not clearly informed that a monthly subscription would start after 48 hours. When I emailed FileWorld, I received a response stating that I had registered for a 48‑hour trial at €0.60 and that, according to their terms of service, a monthly subscription of €39.95 is automatically activated after this period if not canceled. I repeat that I used the service once and canceled right after use, and I did not intend to subscribe or be billed further. In light of this, I request a full refund of the $39.95 (equivalent to €39.95) that was charged to my account and confirmation that my subscription has been fully canceled so that no further charges will be made.
