Unable to Purchase Brawl Pass Plus on Brawl Stars

I tried to buy the Brawl Pass Plus for my Brawl Stars account, but I got an error message saying, "No more purchase rights on accounts with parental controls." If I am unable to purchase the Brawl Pass Plus, I would appreciate a refund for the amount I have paid. If the refund isn't processed, I will take additional steps. Hey, could you please take care of this problem as soon as possible? I'm either looking to get the Brawl Pass Plus or receive a refund for my purchase. Thanks!
