Horrible service - Samsung SA

I am deeply disappointed with Samsung South Africa. I purchase the 9kg washer/dryer and within the first year a fault was logged, since then 6 technicians have been out to have a look at the machine and do repairs. The washer/dryer was then taken and I was left without the machine for over a week. It was then returned with the same problem and extra problems, making this the 7th fault/ technician coming out. I am disgusted that Samsung can’t call me to have this resolve as the machine is still under warranty and I feel that it needs to be replaced. All my appliances are Samsung and I am really considering changing my brand of appliances as their service is disappointing and makes me worry about my other appliances.
