NO CUSTOMER SERVICE...AT ALL!!!

I purchased a Samsung 46\ LED 3D Smart TV (along with the Samsung mini docking station) for around R12 000 from Dion-Wired in Blue Route Centre on the 22nd Dec 2012.<br> <br> This TV has now failed: the bottom half of the screen has dimmed/darkened while the upper half of the screen is still perfect. The TV never fell and has never been abused. It available for any inspection if there is any doubt.<br> <br> 1) How can a Samsung product of 3 years old fail completely to a point of complete replacement?<br> 2) How can a Samsung product/manufacturing failure consequently cost me an entire replacement panel/screen of almost R7500 as quoted by Liptronics in Cape Town
