Faulty 60inch 3D tv after 17months

A week ago i phoned samsung to report my tv have a stripe from the top to the bottom and its only 17months old and still under warranty . They said 'indraf' will collect and fix it. They refused to collect it and i ended up paying a campony to help me get it there. A day later they called to say it is fix they only serviced it. I refused and said that there is another problem a bit of dust cant make this problem. After phoning william de beer from your service department and getting in an argument with him we ended up collecting the tv again. And now 3 days later the stripe is back. It's unacceptable for me. Paying R15000 for a tv and now i must struggle to get it fix. If you cared about your loyal customers the tv would have been replaced with a new one or at least been properly fix. I cant go through the trouble to take and collect the tv again. And another point, now it is weekend and nobody wil go through the troubles to help me.
