Bad service / bad attitude

I have a sumsung note 5 which is 22days old. Was playing games on the device and it over heated and due to this over heating it caused the device to crack at the back. <br> <br> When i took it to sumsung riverhorse valley the manager insisted that i had dropped the phone and made as if i am lieing about the overheating. They did not offer to test the device and insisted i use my one free screen change. My screen was not cracked but the back of my phone is due to the over heating.<br> <br> This moves me away from purchasing any sumsung product as i am really disappointed with the service i received. <br> <br> I had also contacted sumsung south africa head office asking for the regional manager to contact me... till now no one has called me.
