Most of the time, a cancelled invoice is due to being labelled as fraud. We either have our region lock enabled, or there is a mismatch on your credit card information with the Geo location’s network.
If your card details match your account and you didn’t use VPN, you may contact our support team and send us a photo of your identification so we may forward it to our admins for the release of a fraud order if you wish to continue with your purchase in Z.com.
