Hi Passakorn,
Thank you for getting back. I completely understand the situation. Let me see what is the best that I can do for you.
Passakorn, I suggest that you continue communicating with the app developer as they are the only team who can assist you with this an they will be able to provide you assistance on why you didn’t receive the In-App.
To contact the app’s developer:
