Locked out from changing account email

I created this account yesterday with musecore pro, but I accidentally used an email that I'm locked out of. Because of this, I can't access the settings (to change account email), since that requires email verification. How can I change the email on this account, so I'm not locked out of an account I'm being billed for?

Attached is a screenshot of what I see when I try to access settings. The "the support team" link is broken as it redirects you here: https://musescore.com/components/support/contact/select-topic, which is a blank page.
