Double debit on one ticket by MANGO, worst airline in South Africa

Mango airlines has got to be the worst airline I've ever purchased a ticket from On Monday 20/01/2020, I booked a ticket to Dbn and back, the system froze and then I received two confirmations of tickets purchases and a DOUBLE debit off my account. I also did not receive any approval or rejection message. I then emailed refunds and enquiries, with no response up till date and the call center never answers the phone. I WANT MY SECOND DEBIT BAC**** This will taken to all social platfoms as well. I never fly mango and now I know whay I always fly SAFAIR, SAFAIR is convenient and gives a great customer service. Mango, you do injustice to customers and I will promote your failure everywhere.
