TV not usable

My mother did a lay-buy for a 49" Samsung TV in December 2018. When the tv was paid and they took it home. After the television was opened, placed on the stand and switched on the television went blank after a few minutes. We switched the television of and when it was switched back on there was cracks under the screen.

My mother went back before the 24 December 2018 to enquire if they may return the tv to the store and the consultant smiled while informing my mother she waisted her money.

We logged a complaint and the manager Joeylize Williams went to my mother's house to inspect the tv. While inspecting the tv she touched the screen and the crack became bigger. She immediately said this is a factory fault and my mother was told to return the tv to be reviewed.

The manager calls her now in this week and informs my mother they are not fixing the tv as it was damaged by us and we need to fetch it from the store after advising this is a factory fault and acknowledging we did not damage the tv.

We requested them to replace the tv or give us our money back but they are avoiding it.
