Refused to Honour online ticket purchase

On the 22 Sept I travelled to JHB from Durban with my infant son, I purchased the tickets online through [URL Removed] who then forwarded my details through to [URL Removed] for payment. No problem there, I received booking confirmation of flights from Wegolo, Cheapflights and Mango. I confirmed that the correct amount had been deducted from my account - no problem. Arrived at King Shaka Int at 5:30 to check in only to be told that although the ticket had been paid and my details were correct, the payment details on Mango's system did not match my credit card. I had to purchase another ticket. Although this was a hassle the saga does not stop here. \Phone this number for a refund - ***"I tried for two days to get hold of them with the phone been put down as soon as it was answered. Eventually got hold of Customer Care and was told that they have been having issues with [URL Removed] and I must claim the money back from them. Nice - so I have a booking confirmation from Mango themselves with confirmation of payment"
