Samsung TV

Good Day I purchased a TV in December 2015. I noticed that the boarders had a yellow fade into the screen that was uneven. I called Samsung and a job card was filled out, Samsung sent technicians out, to replace my screen but the new screen had the very same problem. The technician said he would follow up... I received no response. I then called Samsung again and created another job card after waiting for them to call. They sent an assessor to view the TV followed by a technician. This screen had the SAME problem. I was then told it was pixels on the screen and that they would have to replace it again, which took ages for them to communicate and never happened. Deon Jonker then gave me an additional 12 month warranty. When they replaced the screen for the second time, the technician over-tightened the *****s for the legs and stripped the threads. He tried to fix them by wrapping masking tape around the *****s... I was then sent panaservice from Makro to fix the TV WHILE ITIS STILL under Samsung warranty. Every time I call, no-one gets back to me and they try pass the problem on. The screen has a blue stripe across the top boarder and Samsung is still "investigating". IT HAS BEEN TWO AND A HALF YEARS! and the TV is still broken WITH YELLOW BOARDERS, NO LEGS AND A BLUE STRIPE.
