Takealot refusing to acknowledge a faulty Acer laptop

I recently purchased an Acer Swift 3 laptop from Takealot. After 3 weeks of daily use, one day the screen decided to remain blank. I.e. it died. Naturally, my first course of action was to plug the laptop into a power source and try again. Besides seeing power lights on the side of the laptop, nothing changed. - the screen remained blank. After >2 hrs of charging I tried again to turn the Acer on. Again, nothing changed. I called the Acer support line and an agent attempted to help me reset the battery. Once again, nothing changed. I returned that device to Takealot. After their evaluation, they officially rejected my return. Their reason? "no fault found as the item battery is low and just needs to be charged". After my own attempts to fix the problem initially, this makes absolutely no sense! This situation reeks of a laptop with an intermittent fault - which will potentially give me years of nothing but trouble! I have requested a credit, which means that the next laptop will still be purchased through them. But NO, they are still attempting to return the faulty Acer laptop to me. I have thus far refused delivery from the courier and the laptop is now back with Takealot. Come on Takealot, after years and years of good products and service from you, please don't spoil a good record. Allow me a credit and I will purchase the "new" laptop from you.
