Brawl Stars Brawl Pass Plus Rewards Not Loading

I purchased the Brawl Pass Plus for Brawl Stars, but the rewards are not loading into the account. Despite sending emails and submitting support requests through the game, I have received no response. My child was eagerly waiting for the rewards after spending money on the game, but nothing has been credited. This situation is extremely disappointing, and I urgently need a solution. Please address this issue and resolve it as soon as possible.
