Lost luggage

On the 24 December 2021 I booked with flysafair from Durban to Johannesburg on arrival the airline lost my luggage. Only to discover after hours that the luggage was left behind in durban and they promised to deliver to my given address. It has now been 24 hours and my medication it inside the bag, no one has taken any responsibility to contact and update me. I keep on following up with no positive response. Flysafair has failed to meet customer expectations in terms of service quality, response time, or overall customer experience and I would never recommend anyone to use this airline.
