LG refuses to fix TV under warranty

I bought my TV in January of 2015 and since about 4 or 5 months ago I have had a problem with my TV restarting itself randomly. I have tried phoning Tafelburg (so they could fetch and bring it to Western Cape TV, subcontracted by LG) to replace the TV (which is still on warranty until next year January) and they returned the TV a month later in the same condition. They did not even attempt to repair the TV after keeping it a month. I have contacted LG and they refuse to help me get my TV working OR to replace my TV. Tafelburg refuses to help me and Western Cape TV are just as useless. When I spoke to an LG representative she told me that it is not their problem and Tafelburg should sort it out. LG is extremely disappointing to sell me a TV that does not function correctly and then refuse to replace the unit when it fails less than a year into a 2 year warranty. I have been struggling to get it fixed for a few months now to no avail. LG has zero customer support and do not honour their warranty. This proves the poor quality of the device and the poor customer care too. This is disgusting service and now I have a broken TV that is still in warranty that noone will fix!
