Shocking service mango airlines

Terrible experience flying with mango arolines last thrusday 26/7/2018. We waiting to check in for a flight that was to depart at 10.40 to Durban in a very long line, eventually decided to leave the line and self check on only to find out we couldnt when we queried we where told by the manager that it close at 10 and we where 10 minutes late hence we had to check for another flight. There where over 10 ppl on that flight who she insisted where late but we all where at the airport well in advance and when we told her that how can all of us be late and arrive at the same time she said even of 50 ppl are so called late they don't care. We had our 3 year old and 8 month old kids so we where forced to pay an extra 2300 to get onto a standby flight so in toltal that flight cost us 3600. We where forced to pay extra because the manager claims she stood at the last counter and called out for all the ppl to come to the front who was on our initial flight prior to closing it. How can she call out using no speaker or not even walking around inbetween the lines ? It's obvious people wouldn't have been heard because it's so noisy. It's very disappointing because we where treated so bad and everyone one of us there was told sorry u have to pay extra or leave , ladies with kids, an elderly women. What happen to those Ppl who didn't have the extra money to pay for standby the most shocking part is when we where paying to the very next flight we got place on here was another queue of ppl waiting to get onto a standby flight because they supposedly missing cut off. Mango now did all off us really miss cut off or is this a way you make extra cash to compensate your cheap flights. So many people had to rebook and your staff didn't have a care in the world.always flew mango but will never booked them again.

This was sent to them almost three weeks and they promised to call me back and till today Im still waiting
