Mango PAY BACK MY MONEY!!!!

i booked a flight on the 19 August 2015 with Mango Airlines and i did this booking online payed with FNB cell point and the money was debited from my account but when i called the Mango call centre for my booking reference number i was told that my booking was UNPAID in their system, but the money was gone from my account debited by mango Airlines. so i was told to email bank statement and ID copy but still until today i havent received my money from them and i phone their refunds departments and no one ever picks up the call. i am wasting my airtime here. i send emails no response. so i dont know whether i should open a case at the police station because it will be a month now and still nothing. They are quick to take the money but now cant pay it back!!!<br> <br> <br> <br> I WANT MY MONEY MANGO AIRLINES.
