Tv screen damaged

I purchased a Hi sense 55inch smart tv about 6 months ago.All was fine until 6months later,the tv was rebooting on its own and freezing continously.Tv comes with a 4 year gurantee which was included in the tv manual.Logged a return,made sure it was packed properly.Skynet picked up the tv and takealot contacted me,saying they sendin the tv back and they cant find anything wrong with it.I contacted Hi sense and they sent me a software update to update the tv.Tv was returned and my brother and i unpacked it and we switched it on and we noticed lines and a cracked screen.So i took a picture and emailed it tru to takealot as well as i foned them and they said to log a new return and it seems as the tv was damaged by the shipping company.So i repacked the tv with the same packagin they sent it with.Now after few days i get a email saying that they cant do anyting and the gurantee is null and void cos its my fault.They sending the tv back to me with the cracked screen.When it was sent to them the screen was perfect,upon returning back to me it was damaged either upon shipping or at their warehouse.This is unaceptable.Tv is still brand new.Never even remove the clear packagin on the side of the tv.On top of it the tv costs Almost R7000.What do i do now.Tv Screen was damaged eithee via shipping or at the warehouse.Tv screen was perfect when i sent it in.
