[dui宝QQ糖]

Hello, I am a loyal mobile game user, the account ID is: 3o1u-5i6mz. I'm here at 2877697046@qq.com and username: dui宝QQ糖. Something very important is happening in the game right now. I just bought the BLOSSOM RELIC 10+1 chest for 5000 diamonds. However, after the purchase, I accidentally returned the game before opening the box, so I did not open the box, but spent 5000 diamonds, now I am very sad, please help me solve this problem, and hope to reply to me in the game or email in the mailbox, I will always pay attention to this matter, and hope to get a reasonable feedback, thank you very much
