Bad Bad Service

My Daughter visit me in JHB .. she returned on Mango Flight J133 ref number MMSPYN her luggage was over weight by 10 kg we paid additional R 450.00 R45 per kg we also specified that the bag was to be put in fragile luggage , which was not the case we told the clerk checking my daughter in that there are glass bottles in this bag. I feel as this airline does not take care of, in this case the luggage of passengers. I believe that something did not seem right , as my daughter phoned me and told me the bag marked fragile, and her suitcase was damaged this is unacceptable therefore I am not going to leave this. Mango Airlines. I therefore request that Mango Airlines should be hold responsible for these damages ... I need Mango Management to investigate what went Wrong .I do have photo's of these luggage items . please contact me urgently.
