Mango Airlines - Absolutely shocking customer service!!!

On the 8th October, 2 weeks before our flight to Cape Town - for my son’s wedding, Mango cancelled our midday flight and put us on a flight leaving at 19h30. No phone call regarding changes and whether the time is suitable. As the main passenger, I just received an sms notification. The flight leaving at 19h30, was not suitable as we had to attend a function at 18h30 in Cape Town. I notified my son, who had paid for the tickets. My son called Mango, enquiring about the changed flights and was told our original flight was cancelled. My son said the changes are unacceptable and cancelled the flights for 3 passengers. He was told that the money would be refunded to his account. A week later my son followed up on the refund that had not been received, he was then told it takes 14 days. This should they have been in his account on 29 October 2019. By 1ST November, he had still not received his refund. Absolutely shocking service… Total Incompetence. My family and I will definitely not be flying with Mango Airlines again!!!
