Samsung sucks! Two weeks ago two Samsung techs visited to look at our 2017 refrigerator that wasn't getting cold and made a loud grinding sound. Of course, it worked and sounded great when they were here. The techs did nothing but charged us $140 for the service visit. The the senior tech did say that if something went wrong in the next 19 days the next visit would free. So two days ago the grinding sound came back worse than ever. Called Samsung to get another tech visit only to be told that the last ticket had been cancelled and that we'd be charged another service fee for the next visit. Utter BS. The attendant did not allow me to speak to a supervisor and kept me on the phone asking me the same questions over and over and over. Samsung sucks. Their appliances are cheap and their customer service non-existent. DO NOT BUY.
