Misload of luggage and no care or after service

Several other passengers and I departed from OR Tambo to Cpt on flight JE135 on 25/01/2019. When we landed at 13:10pm some of us were told with no care in the world that our luggage was left in Jhb and we might get it later or the following day. None to say it's after 11pm and still no luggage received. When I called luggage assistance in Cpt and the national call center earlier the phones were not being answered and now all we get is an automated voice message telling us about Mango office hours. I am left in another city stranded without my personal clothing (including underwear) and having to deal with an airline that clearly doesn't care about customer service and the fact that you have to communicate with your customers to let them know what is happening with their luggage that THEY left out from the airline! All I want is my luggage and in tact! I had commitments that I had to attend to and I couldn't as guess what... I have no luggage or clothing. Mango Airlines owes its customers an apology and I'd like for this to be resolved urgently
