Solution

Please follow these steps to change your Google account for in-app purchases:

1. Uninstall the app 
2. Then go to the WEB BROWSER VERSION of the play store
3. Add the account you need to your device. (Settings -> Google -> Account -> Add account)
4. Check the account tab in the Google Play menu to Make sure you're logged into the right account (very important)
5. Then find the app/game and download it from there
6. Wait for it to install. 
7. Open the app and try making the purchase again.

Or you can follow the steps below - 

1. Go to settings -> Google -> Accounts 
2. Click on other accounts that you don't want to use as payment account. 
3. Click on remove account 
4. Make sure there is no other account available other than the account that you are gonna use for making payment. 
5. Now open the app/game and try to make the purchase. It will surely work.
