Terrible Customer service from Samsung

I am relatively disturbed, and outraged with the service of Samsung and their repair technicians , I encountered imperfection with the TV I purchased in 2017 Nov and most certainly under warranty , the screen is picking up poor reflections, and lines across the TV , such poor viewing and this is categorically unacceptable as I paid cash and quite a considerable sum for the 3D smart T.v and the duration of usage should be valued for at least, 5-10 years of service, as I only watch TV mostly on weekends due to work constraints.

When this occurred I immediately contacted Samsung and complained They had advised me that a repair person would resolve the issue within 7 days .The technicians came and investigated and mentioned that the screen is "Physical damage" which to my knowledge has not been tampered with and no visible screen impairment, This is Just ridiculous that I have to accept this as They solution ! They Had taken pictures and left with My T.v still with the lines and blury vision. They had told me that Head office will call me in the next 3 days.

There has been no1 from head office who had attended to my complaint which is going on its third week now and they have not called or emailed with regards to my situation of my T.v I really do wish I get some assistance with this post as I am seriously thinking of changing my brand of appliances from Samsung with this real bad customer service provided to their loyal customers .
