****** Wallet at Mango Flight

I just flew Mango Airlines flight, JE284 from DBN to JHB on the 28 Feb. I put my wallet in my luggage as I didn't have pockets and not much luggage. At reclaim in at OR Tambo... My bag came opened and my wallet was gone. Please help me get my wallet from the Mango Airline people. The Lady on Duty couldn't help me at all... All she did was call and say it's hopeless they never find them anyway. And she gave me a number to call of the big gage Manger called Brenda on ***
