Fileworld Charged Me €49.95 for a Subscription I Never Authorized

I was surprised to discover that a subscription was activated on the Fileworld website without my knowledge or consent, and an amount of 49.95 euros was deducted from my account. I did not knowingly subscribe to any of their services, and I do not know what type of subscription was started. I did not enter any bank card details on the site, and I did not receive any message or notification informing me that a subscription had been activated. The amount of 49.95 euros was deducted from my account at Al Rajhi Bank in Saudi Arabia on the 3rd of the month at 2:48. This deduction was made without my prior knowledge or approval. After noticing the charge, I sent an email to Fileworld to object to this unauthorized subscription and payment. I request the immediate cancellation of this unwanted subscription and a full refund of the 49.95 euros that was deducted from my account without my consent.
