Mango, thieving airline

We could not check in for our flight as the lady said it was too late and they were already boarding. The flight had not left yet and gate did not say it was closed so that made no sense to me.<br> We were then informed that we could not change our current tickets and had to buy new ones. The lady that helped us was so rude. she did not put the correct birthdate in and I had to call the center to change it. she also did not pick up that our edgars card we used did not clear. we picked it up not her and we had to go back and buy new tickets on a credit card. the next morning the manager told us we could have changed the tickets and did not have to buy new tickets at all and that the lady that helped us was incorrect. there were flights out after ours, but the lady that booked the new tickets **** to us and said there were no flights for the rest of the day. while we were standing there crying, the one lady sitting next to the agent sat chewing her gum (how professional) laughing at us while saying something in Xhosa. what kind of service is that?? not acceptable at all. I would not recommend Mango to anyone ever. and will take my story to the media if not refunded
