MANGO AIRLINES WORST AIRLINE EVER

Never used Mango before and never will again!!!! Book a flight to DBN at 06:45 to be at a meeting at 10:00. Received an SMS from Mango to let me know the flight has been moved to 14:45 (eight hours later). Been put through from one department to another, no refund and Mr. Molefe who answered the phone doesn't give a ****. Sorry no managers they are working from home and sorry they don't have cellphone's I can give you an e-mail address. Mr. Molefe clearly does not realise that I need a response today!!!! No refund will be given, but I can get a credit. Seriously Mr. Molefe who will ever TRUST Mango to fly them anywhere???
