My In-Game Money Keeps Disappearing in Hay Day

I play Hay Day on Android, and for the past two weeks, every time I log in, a large amount of my in-game money disappears. So far, I’ve lost around 60,000 coins, which cannot be explained by my spending.

I have never used any third-party apps or cheats, and I have not made any in-game purchases. The problem started on its own and keeps happening every time I enter the game.

My account ID is: #LV22L8RVP.
I request a full investigation of my account and a refund of the missing coins.
