Damaged bags

Overall I like Mango. There is just one thing I do not understand.<br> <br> Last year I boarded almost 30 flights for work and non-work related reasons. I flew with Mango, Skywise, Safair, Comair, SAA and Kulula.<br> <br> On all the flights my bag (or my travel companion's bag) was not damaged, except for four instances. Either the handles or the wheels were damaged. All four instances occurred with Mango. The first three times they were willing to help, but the last time they refused to attempt to repair the bag.<br> <br> My conclusion, Mango staff does not take care of luggage and it has escalated in such a way that they have stopped repairing the bags due to damaging so many of them.<br> <br> Why can the other airlines take care of my bags and Mango can't?
