Dear Leader,
I’m very sorry to hear about the inconvenience.
We've investigated many time about this issue, but it doesn't appear to be an issue with Heroes Charge itself. It seems to be in the connection between the App store app and the Apple servers.
One thing I suggest to people is to sign out and back into your Apple ID in your iPhone/iPad's Settings under Store.
In general, it’s best to contact iTunes Support for these issues. People have also reported success with logging out and back into their Apple ID or resetting their Network Settings on their iPhone/iPad.

You can also try to reboot your iOS device and make purchase again under a more stable internet environment. Thank you!
Regards
Allen
