Mango treat your customers better!

Mango Airlines were terrible to me on Monday. I booked a morning flight in order to make it to a meeting I had that day. This flight was booked just after 1am. I got a reference and checked in online. The morning of, I get to the airport, go past the security check, when I get to boarding gates they tell me that my flight reflects as cancelled. They don't let me in, they tell me to send the bank statement, I send, the payment reflects. In this time I missed tha flight. I request to be put on the next flight, furious as hell. They agree, but state that I would have to buy a new ticket , and that when their IT guys get there they will check. The supervisor wasnt even showing any compassion. Instead was rude and left me there to deal with their inexperienced staff.But nowI have to call and follow up . My resources should be used to fix this still. As it stands, it's 4 days later, Iv been calling the number they gave me, I'm on hold for the longest time. I'm furious.
