Refund Please!!!!

Hi! I recently got a Musescore Pro + and Lite, now I want a refund. It cost $50.99 (Australian Dollar). I am sorry, I was only meant to get Musescore LEARN Lite. Again I am sorry for the inconvenience, I know it is my fault but could you please consider my problem? And also I searched if I could get my refund if I ask the musescore support after 14 days of purchase. If the refund is allowable, can I get back my $50.99 please.
