Ignored request of a return within the warranty period

After returning the above item within the one year warranty period I was informed that I would have to pay R1200 for repairs. After declining to pay this amount and requesting an explanation I was ignored, and the item was returned to me in a non working condition. Now Takealot agents refuse to give me assistance and keep telling me to contact the supplier but I don't know who the supplier is. The supplier was supposed to contact Takealot to confirm that the item was within warranty. But then again I guess the customer doesn't matter. I understand it's slow going during covid 19 but then again this is bad service. And I will be posting this via social media as well so that it might illicit a response from Takealot.
