Samsung calling the customer" negligent"

This is the second review Iam writing after Samsung phoned me back and is still, of the opinion that I am " negligent".I bought a twenty thousand rand S6 with keyboard a d pen tablet . 5 days later in my hotelroomI opened the ta ,etc to use it, I set it in the upright positionand was going to attach the charger and key board when the backing sudden,y came away and it slid of the desk , crashing to the floor and cra king the screen. So far Samsung has repeatedly told they will not rep,ace the screen as I was " negligent". I am still waiting for Samsung to tell me how am I negligent if I have been using the tablet exa t,y as it is supposed to be used! And I see on various forums this is a design flaw"
