Worst service when it comes to warranty items

I bought a TV while overseas and had it delivered to my home. We got back in august and somewhere along the line it started making little dots on the screen which spread to a line in no time. Called the call centre and they said to log the return. Decided to take it in myself as i didnt have the box anymore. Drove a 160km round trip to their warehouse only for them to say its not their problem without ONE person even switching the tv on to see whats wrong. Ive been emailing and every second email they try to pin the problem on me. I have more than one tv in my house and this is the only one doing it. Asked for a manager to contact me and that doesnt happen. I only get told the warehouse manager says the tv has been in my posesion too long its not their problem. Last email again, wasnt the box moved around alot and i must contact the manufacturer. Why on earth do you sell items with a warranty then do not want to help your customers when theres problems??? R5500 down the drain is no joke! I have never received such bad service from anyone.
