Disfunctional TV

I bought a tv end of May from Takealot and the tv was bought for my mom and I was away from the province and on my return which was the first week of September I hired someone to come and mount the Tv to the wall, the guy then called to inform me that the tv was broken, I still have voice recordings from the person letting me know that the tv was broken, I messaged takealot on facebook and instagram to inform them that I had a faulty tv delivered to me and I was told to send it in so that they can check, I sent the tv through to them and they said they they will not exchange nor fix it since the LCD is broken. Now my question is, if you deliver something to me that is not functional, how is it then the consumers fault, tv was never opened and box was discarded on the day tv was mounted, if my issue does not get sorted out I’m taking this to the ombuds, we work hard to buy these things from companies only for them to take us on a rode like this.I am highly dissatisfied and will not let this rest
