Broken Sansui Notebook still awaiting feedback

In December 2019 I bought a Sansui Notebook at the Incredible connection Cresta branch the notebook gave me issues with the screen disappearing and I took it in which they then advised they are unable to fix they will replace it then got the new notebook and yet again the notebook gave issues with the screen. When opening it, it makes a noise and the screen behind cracked. I took it in on the 24th of December and they said they will sent it in for repairs and if theycant repair it they will refund. I spoke to Jabu on the 4th of January that advised that it as sent in to the repairs he will follow up and call me back, then on the 5th of January followed up and said he will call back and still nothing. I called on the 6thof January and then spoke to Oliver who advised the laptop was never sent in to repairs as they were not open yet so Jabu basically ****. I want a replaced new laptop or my R4000.00 back. Slip MBI486676
