Don't use VPN/devices that are detected abroad. 3. Not currently abroad. 4. It is recommended not to use a new Gmail account. ================================ to avoid error codes with descriptions (requires more info) 1. Make sure your Gmail account has/often redeemed the Google Play code. 2. If you are unsure about your Gmail account, you can first try buying a GPC 5K to test that your Gmail account is healthy. 3. If you buy more than one voucher and the first time you try it has an error/requires other information. DO NOT CONTINUE WITH THE SECOND CODE because you will get an error too. BE SMART BUYER THANKYOU.
