A negative Gems/Diamonds balance may occur if a refund is requested on a used in-game Gem/Diamond purchase. When the refund request gets approved, the respective Gem/Diamond value of the in-game offer is automatically deducted from the account. Offers in-game are often valued higher than the price you pay. That’s why the number of resources removed from your account may be higher than the original cost of your purchase.
If no refund was requested, the problem might be that the payment didn't go through, and an automatic refund was issued, resulting in an automatic refund of the respective Gem/Diamond value. If that’s the case, please contact Google or Apple to check your payment status.
