warranty

Recently i took my Samsung Galaxy S7 in to Samsung store Tygervalley because it stopped working. As it is still in warranty they did a diagnostic and said the motherboard needs to be replaced. I then boomed the device in and they send it away for repairs. Then they send me a quote of R5700 for screen repairs etc. I then rejected this quote saying that the screen was working and only the motherboard is the problem. They then informed me that Samsungs policy is to fix everything or nothing at all. I find this attitude disgusting and believe this is just a way to get out of their commitments. So be carefull of these ******** and their so called warranties.
