Bought various devices convinced by the offer 10-year warranty.
At the first phone break to the assistance and serficamente answer me that the guarantee is on the assembly! I protest and to my complaints they send me a technician who for 50 dusts me all the conditioner and tells me that a piece of Samsung is needed and I will be contacted for the repair.
More than a month has passed and nobody has been heard.
really a misleading advertisement and a fraudulent service.
