They lost my luggage with my medication and all of my clothes and shoes.

I did not get my luggage from a flight from Port Elizabeth to OR International Airport. I have been going to Menzies (Company dealing with the luggage) and following up with FlySaFair with no luck. Just a come tomorrow and " she says she will bring it" Now I have underlying health issues and I need to take my medication everyday without defaulting. I have defaulted for a full week, yesterday I collapsed lastnight and had to be admitted to hospital because of my blood platelets had dropped because my medication is in that suitcase. The passenger is refusing to bring back the luggage and I have just been told that there's nothing they can do. WOW JUST WOW!!! I will be sharing this in all social media platforms for awareness. I will never trust or fly with you people ever again.
