Mistreated and Humiliated by a Samsung technician

I am very dissapointed with the service i have received from this Company. My Samsung 13kg machine I bought in on the 20th November 2018 is not finishing its cycles. The technician that was sent to me by Samsung was very rude to me. For one he did not want to listen to anything i told him. He is telling me about the level of where the machine is currently places as a problem. I explain to him that the problem did not start in this new house I currently moved in. The technician shouted at me like I am stupid I dont know what I am talking about. He started shouting at me and dropped off the phone while I was still talking to him. I have never been humilated by a service provider as this technician did. This incident happened in Pietermaritzburg Lincoln Meade.
