UNACCEPTABLE CUSTOMER SERVICE

My family and I had booked tickets with Mango to fly to Cape Town on the 27th February. We arrived at the check in at 16H45 for our flight at 18h30. We unfortunately forgot the card which I paid for the tickets at home. We did however produce all other necessary documentation like identification documents for all of us as well as proof of the credit card payment which reflects on the credit card statement. (The supervisor asked where the reference number reflected on the credit card statement). I asked for a computer or an internet cafe to access my email where a copy of the credit card was kept but was brushed off. The payment was made on the 20th January 2015 and the invoice reflected a ZERO balance and yet the supervisor was not prepared to try in any way to resolve this matter for us. Taking into account the time that was still left before the boarding gates closed, this matter could easily have been resolved. We had to forgo our attempt at being assisted and left the airport at 19h00. We had to be at the airport by 5am the following morning to go on standby and had to park our vehicle at a cost of R500.00 till Monday the 2nd March. I have yet to receive a response
