That's so annoying! If you're an Android user, we may be able to get you a refund, or if you use cloud save, we might be able to give you your well-deserved items or currency in-game! 
We're afraid that if you are an iOS, Amazon, or Windows user, we won't be able to give you a refund. However, we might be able to help by looking into your save file if you use Cloud Save. It would help us out a lot if you could provide your Cloud save ID along with the receipt of your purchase.
