Samsung dont care

I took my samsung note 4 in for the 3RD TIME to the samsung customer care centre in Constantia, on Monday 5/10/2015, as my phone just would switch on. I requested a replacement as the phone has been in 3 times in this year. i was advised, that they would try to arrange a new phone if possible. Last I heard from them was on 7/10/2015, saying they are ordering parts via sms. There was no mention of a replacement phone. Since then I have heard nothing. I am really disgusted with samsung and the quality of their products. When you call nobody answers, all five numbers.
