MuseScore PRO+ Query

I claimed a Black Friday MuseScore deal last year, where MuseScore offered PRO for AUD$0.01 per week. The fine print at the bottom of the deal stated that this 1 cent fee would be charged until cancellation. I have recently noticed that this price has increased to AUD$3 (file attached shows proof of this). What should I do?

Here was the fine print:
By clicking the 'Claim this Deal' button, you agree that MuseScore will automatically continue your membership and charge the weekly membership fee ($0.01) to your payment method until you cancel. You will be billed within 2 days to 6th day of every week. To disable auto-renewal, go to 'Subscriptions' in 'Settings'. Access to some scores may be limited. Free trial is not available for users who have already tried PRO, PRO+, PRO LEARN Lite, PRO+ with LEARN Lite, or ONE subscriptions.
