If you happen to have a purchase issue all you have to do is to follow these steps:
  1. Open the in-game shop again and tap on the same item. If you see a popup “Unfinished transaction; you have one or more unfinished transactions.”, tap on button "Complete" to claim your item. If you do not see this pop-up message, proceed to steps 2 and 3.
  2. Go to your email, you will find a receipt from Playstore or Appstore
  3. Forward this receipt to our support email, along with a copy of the payment method. Please have patience, we will reply to you as soon as we see it, so don’t worry.
