Missing Arena Rewards - Electric Blueberry

I am writing because I have reached over 500 crowns in the current Arena season, but I have not received the Electric Blueberry rewards.

My Player ID is: 81772598-6527-4C91-B782-2B6660F9B824

Could you please look into my account and help me restore the missing rewards? I have attached a screenshot of my Player ID and my current Arena progress for reference.

Thank you for your help!
