If you successfully made a purchase through the Google Play store and your coins were not added to your balance, something you could try which usually works is to completely close out the app and then reload it.

Sometimes it can take a bit longer for the Google Play servers to sync up with our own, and this restarting of the app can jump start that process.

If you have tried this and your coins are still not reflected in your balance, please contact us so we can manually add your purchased coins.

It will also be greatly appreciated if you could provide the Google Play store purchase receipt when contacting the Support team.
