Bad service ever from Ntokozo Simelane and Edgar the technician.Dont but their appliances don't ever

I bought a 7kg washing machine end of July 2023 i only do washing on Saturday I did my first load and I thought there is something I am doing wrong the white cloths came out dull...i tried the next weekend thinking I am the one who is unable to operate the machine. I noted when finish washing there will be foam and my cloths come out like there was staysoft I was puzzled what could be the issue. Then I did the extra rince that is 30 Min then I found out my cloths are no rinse properly. So now I had wash for 60 Min and do an extra rince for 30 Min that was pathetic. I lodged a call that the functioning on the machine I am not happy about. Ntokozo Simelane said she will send technician to check the washing machine and the guy by the name of Egda came and run a 15min circle and do a report saying there is no fault. I said again there is no fault but I can't be doing a one load for 1and 30 Min because the washing machine doesnt rinse out the soupy water first before pulling the water with staysoft or fibric conditioner. Then Ntokozo told me I must try 9kg as it had more options and they brought the machine for me to try . They brought an old machine and Edgar connect the machine he left the place so dirty and run a 15 Min circle and it was proven that this machine rince only once we took pictures and send to Ntokozo with Edgar . Then wanted to try a longer circle as I am only doing washing on weekends . Then the washing machine they brought to my house is liking . I would see the leakage the day they brought the machine as they left the place so dirty then I finish work I cleaned out thinking it just water from the pipes that on the floor. They refusing to give my full refund but the Edgar guy confirm with me that I am not the first person to complaint about the rinsing of the machine. Then he suggest I must with pre wash them wash do I will do one load foe two hours as I want my cloths to be clean. Ntokozo doesn't have customer services she is busy telling me about the refund process I bought a machine for washing but I can't be doing washing the whole day coz their functioning on their machine is not correct or working properly even the top loader rinse out the soupy water then rinse with fabric softer. I only done one load I don't have washing machine as the machine they brought to my house is liking .
