Poor service

On the 26 August 2015 I purchased a Samsung J5550K home theater system. My requirements was a Samsung product with tall boy speaker with power output of 1000 watts. I setup the product at home and only two front speakers are working. I call Makro and I'm told I can only achieve to get all speakers to play when a play a content of digital Dolby format. I returned the product as it was not performing as per my expectation. I meet Jimmy moloto who took me for a fool. He change the setting to game mode to get all speakers to play. I asked him why would I play everything on a game mode he then said he can't assist any further because all speakers are play and I'm still not happy. Why would I buy a product of six speakers and only listen to two, why would I play music or any other content on game mode? The attitude and behaviour of Jimmy and Louis just doesn't belong to any business. Louis guy took the product off shelf and put it on a trolley and that was it. He doesn't even know how to change setting in a remote control and had the nerve to say I must take the product that will only play all speakers on a game mode. I had to suggest whether I could get another product
