Poor customer care for TV in warranty

In January this year I had purchased an LG TV from Tafelburg Furnishers. Since a few months into purchasing this new TV it had started restarting itself at random intervals. Eventually last month I called LG in order to get it fixed (not even half way into a 2 year warranty). I had received a job number and had been promised a call from Western Cape TV on Monday as it was the weekend at the time. A month later my TV is still giving problems so I call LG again. LG have decided that they do not care about fixing my TV even though it is still covered by a warranty. Whoever I contacted at LG had attempted to fix the error but obviously the company that LG uses is useless. What seemed simple to arrange over the phone, to get the technician to come (I was even told for first call for the day) and to organise a loan TV. Western Cape TV had promised to deliver the services before I leave for holiday, due to how long I waited. The next day at midday (is this first call?) I am informed by Tafelburg Furnishers that nothing was done about the loan TV and I refuse to send my TV away with nothing because judging by their service it could be another month before I hear anything back!!
