Horrible. Stay far away.

Horrible. Stay far away.
I ordered a ticket through them and called them after may card was charged to confirm that everything was in order. They confirmed that everything was fine.
A day before the flight at 3:48 AM I get an email that I need to send a proof from the bank by sms that I'm the legit owner of the account. Less than 3 hours later at 6 am, I get a second email that my flights were cancelled.
I called Flightnetwork and they said it was cancelled because I did respond to the email.
Were they expecting that I wait up every night, the entire night in case they email me for verification.
