Monopoly Sudoku removed over a $100,000,000 from my winnings account.

In Monopoly sudoku when I started the game yesterday it had removed about $180,000,000 from my total money account. It has not returned. WHY did it disappear?  I was approaching $1Billion. I dropped from $910,000,000 to $809,000,000. Please return the money I earned. I have been using paid for power ups hundreds or times. I am awaiting the airport level to open. Thank you.
