Very bad service quality!! Never buy the samsung washing and dryer maschine WDO704REU, just waste your money. The service center staff are incompetent, unprofessional, not reliable and not trustable. They do not know what a problem the machine has and they always promised to come, but they did not come. I bought this maschine 1 year ago. After 3 months the maschine broke down all the time. I called the samsung customer service center and they said the service center will call me and will send someone to come to my home to repair, but I waited and waited, nobody called me. After 4 days I called again and finally after 1 week the service center staff, they came and had a look at the maschine in 5 minutes and promised to come again. And they did not come, after 3 days, I called again and finally after 1 week they came to repair. 2.5 months later the machine did not work again and the whole story was repeated again. After about 1 year and 3 weeks (when the warranty ended) the machine broke down again. The service center staff came and did not seem to know what a problem the machine has.They told me to replace a walve water and it is not cheap: it was 425AED, after the replacement the machine does not still dry: I still have the same problem. I called them again, they promised to come, but did not appear. I called and waited and I am still waiting but they do not come.
