Unable to contact support

I have been trying to contact support because I have been charged too early for my renewal of Musescore. I encountered a hard stop during a practice session with my band and was unable to continue unless I paid for Musescore again. This happened on February 21,2023. I later received notification that my subscription would be automatically renewed on April 2, 2023. When I try to contact support my email and password fields are greyed out, preventing me from sending an email to support. Any help would be most appreciated.
