Sometimes, the transaction with Apple App Store / Google Play Store may not go through due to server issues, credit card, etc.
If the purchase went through, you should have received an invoice Apple App Store / Google Play Store and you should see a charge on your credit card. If not, you might want to try again to see if that works.
If you feel that your credit card was charged and you did not receive the VPN Premium subscription benefits, please contact our customer support at support@appsverse.com with the invoice from Apple App Store / Google Play Store and we will rectify the issue for you.
