Not so helpful manager, pinning the issue to us

29-1-22 bought a TV Hisense at mall of Africa Branch , TV tested fine, the guys from the store packed it in the car, moment we switched it on the screen had a leak that’s what we thought, took it back in an hour later , we were told the screen has cracked inside ,we should come back following day 30-1-22 to speak to the manager, Jess the manager was not so helpful he told us indirectly that it’s our fault since it switched on in the store, our point is what if the crack happened in the process of packing it? , he told us to go to the ombudsman with confidence that you won’t win this case , I’m so disappointed the least he could have done is replace or repaired this as this cannot be our fault
