Musescore PRO Refund

Hello. So I truly enjoyed using musescore for composing and notating my compositions for college. But I needed the Pro account to view the pdf files and print out some things and dp a few other things that it said only a Pro account could do. So I signed up for the free trial. I don't need the Pro account anymore so I never used it after the one time I needed the Pro feature. However, I forgot about the Pro account and a few days ago $49 was taken out of my bank account. I contacted Musescore through email asking for a refund. But there has been no response. What should I do?
