Samsung has a completely disfunctional service department. I have been sent two shipping labels to send to Samsung's own-choice Authorized Samsung Service Center. Each time Samsung's chosen repair center returned the item to me because the serial number and model number supplied by the Samsung service department to the repair center did not match the serial number and model number on the machine. I do not understand why the Samsung service department and Samsung's chosen repair center cannot communicate directly. Samsung claims it has not email communcation, which is odd for a leading producer of devices that sent and receive email. Bottom line: wasted many hours and phone calls. If I could give Zero stars or negative Stars. I note that Samsung's own website notes it averages 1.2 stars out of 5, and that is too high
