Lost luggage at checkin spot.

I am writing this complaint with extreme frustration and disappointment regarding the shocking service I received from FlySafair. My experience has shown me that this airline has little regard for its customers or their belongings.Yesterday morning I had a flight from Johannesburg to Port Elizabeth for my graduation and I had a checked in suitcase which have my clothes in it but when I landed and it’s time for me to collect my luggage I haven’t received my suitcase I waited at the airport hoping that it’s on the next flight but no luck.Now i have to call for help at the call centre where the service it’s also poor cause I have to use my airtime to make a call because of your fault and guess what?My call might be attended or not now I have to look for another outfit because of you guys. Poor service it’s day two now and I haven’t received my suitcase i have been waiting and waiting for the feedback but no luck they only sent a email in the morning saying they’re still locating my luggage 24Hrs you can’t even confirm that you found it or what ? Should I let go of my suitcase or what? I beg can I have my suitcase please.
