Excuses but no action

Bought a notebook in 2012/2013 in Makro it gave me a problem with a Rom and sent it back in July last year they told me they have 2 charge me for the screen as I damaged it but I never damaged the screen it only showed a spark while working on it,told them they mustnt repair the screen as they were nearly a new notebook said they should fix the Rom.they sent the notebook saying they fixed the Rom when I got home the Rom was still not working I sent it back then they told me that they can't fix the Rom if they can't repair the screen then wheb I asked them why they said from the 1st time that they fixed it.The Manager said he will look at it that was in October up until today he hasn't came back to me and am using my notebook for work purpose and on top of that that's the 3rd notebook from same supplier giving me problems.Makro has a bad service with their supplier.
