Unhappy client

My name is Clement Pillay. On te 27th of September 2019 I made a cashsend R110 from TymeBank app to my son. He never received the money or the SMS but the money was withdrawn from they system. I phoned TymeBank on Saturday the 28. They responds was the cashsend is not operational yet. How can they introduced something that is not working. They promised me refund my money. I am still waiting. Below is my reference:Tyme: Your General Service Request request has been resolved. Case ID G-53058. Help: ***. My case is never resolved.
