hello i want a refund for my VPN master product subscription, how can i do that ?!

Make sure the subscription is cancelled.

Purchases - View, change, or cancel your subscriptions.        

Purchases - Subscriptions not billed through Apple     

Normally, all sales are considered final, but you can ask for a refund.

If you have received a confirmation email, click the Report a problem link at the bottom.
