Bad Repair Service

I have a 3D Blue Ray Home Theatre system, 11 months old and suddenly it stopped working. Phoned Samsung service centre, quite plesant experience. Logged a repair under warranty (ref#: ***), took it to their preffered tech ( Unitronics) 09/03/2015. So far a good experience ( accept the driving distance). Get a call 10/03 stating it is repaired & tested, was the main board...on an 11 month old device? # Concerning!!!<br> Drove all the way out to Unitronics, collect...still a good experience until I get home and connect the DVD player. \Why-am-I-not-surprised""; different cables to eliminate user error; issue still remains. Almost everything in my house is Samsung; from kitchen to living room; a brand loyal cust; starting to doubt my choice now. Truely dissapointed with product and aftercare service. You almost had a Good customer expierence in the bag;right up to the end when it really mattered.<br> """
