Samsung - Not looking after there clients.

My Samsung S6 has been in about 11 times in the last 2,5 years. They extended my warranty by a year. It has been in at Sandton Samsung now as I did not want to go to SSS Services. I am currently using my daughters phone and you can touch screen lightly. Mine you have to just about break the screen if you move the position up or down it might work. It does not always do this. Really I thought they would replace the phone by now. Samsung has really shown very poor service here.
