Unpleasant experience with Mango

It is with great displeasure in which I share my first time experience flying with mango. On Thursday (01/08/2019) I flew with mango from Lanseria to Port Elizabeth and upon arrived I discovered that my hard shell bag had been shattered. I then reported it to the Sokhona (one of Mango’s employees). Initially she was eager to help, she told me that I can leave the airport with bag and that she would contact to by 12:00 that same day, 12:00 came and passed without her contacting, I then drove back to the airport to find out why she had not contacted me. My second encounter with her was completely different, she was so rude and paid no attention to me. The matter was not resolved. I am still stuck with a shattered bag with no way forward.
