After 4yrs of playing, the devs, after my dispute of charges made my gem count -73k. Without discussion or recourse, after days of messages they suspended my account. I hope that no one ever downloads this game or spends one dime on their product. I have deleted my account as I won't be extorted to spend money that was disputed. They suspended my account even though I'd taken 6k off the negative balance. Don't waste your money unless you're a big spender who has money to burn.
