Read before you buy

So I bought a hisense tv with a 4 year warranty on it nearly 2 years ago. it started switching off randomly so I started to try get it fixed. now after it being in 2 times to get fixed I go to game pavilion and get made out that I am lying about the fault as said by hisense THERE IS NO FAULT FOUND ON THE UNIT So I get told that they don't know me and they need to see it for themselves coz they can't trust .me well you would think that if my tv was working WHY THE HELL WOULD I BE WANTING IT FIXED so eventually tv goes to store and guess what it switches off. get a call saying I can get money back which I don't want I want a tv the same as I bought which was 58 inch UHD 4K SMART HISENSE I get told that they can't give me the same version because it's not made anymore and the same NEW VERSION HAS BETTER FEATURES .SO I MUST PAY R5000 MORE to.get the same thing only the new version. COME ON GAME IF YOU THINK THIS IS FAIR AT ALL YOU ARE LIVING IN ANOTHER WORLD. THE NEXT REVIEW WILL MENTION EVERY EMPLOYEE NAMES THAT HAS MADE MY LIFE HELL OVER THESE LAST YEARS GOING BACK TO THE VERY BEGINNING SO I EXPECTED A SOLUTION LIKE TOMORROW OR YOU CAN BET I WILL BE GOING FURTHER THAN HELLO PETER WITH THIS
