MuseScore review: Subscription to sheet music service

On 11/13/2022 I signed up for a free 7 day trial with MuseScore. 3 days in I decided I did not like it and canceled on 11/17/2022. Everything showed canceled so I figured I was all good. On 11/21/2022 I am charged through PayPal for a year's subscription for 69.99 although I did not authorize this and had already cancelled my account. Despite proof, this company is saying I authorized it and will not refund me. A complete and total unethical scam of a company.
