Samsung blamescutomer as negligent!!

I bought a brand new Samsung galaxy S6tab, it cost me twenty- thousand rand. 5days,after when I set it up to charge with the hinge at theback slightly open so I could use it in the upright position, the backing came away and the tab separated with the result it crashed to the floor. I have done all the steps, loggedacustomer complaint,etc and have been told that it is my negligence!! Despite me telling them thT if one goes online it is a common flawwith this design, the magnetic stripat the backof the tablet, etc comesawayeasily despite wiping it clean Iam sodissapointed with Samantha and their customer service and most ofalltobe told I was negligent
