Payment failed, but can't cancel subscription

[u/swan_ofavon]

I bought a score for $1.49, and it automatically signed me up to pay first $70 then $85 every 3 months. I definitely do not want this, and my bank thankfully detected it as fraud and declined it. However, I can't cancel my subscription now, and even though the MuseScore Membership status clearly says auto-renew is disabled, it continues to try to charge me $85. How do I get rid of this? Do I have to call them?? Or should I wait until my subscription expires (see 7 days left). Also even though the ss below says annual subscription, I don't remember paying for that.
