Received tablet with damaged screen

I sent my tablet to TRU due to charging issues and the screen got broken in transport by Skynet. The screen was then repaired by Laceys as they confirmed it was broken during transport. Upon collection at TRU Mall@Reds Keshan opened up the tablet and switched it on. Immediately I told him there is something wrong with the screen. It was loose and also had dark spots. After reporting this numerous times Judy contacted me and assured me that she will get it sorted out if I have any issues with it in the next 3 months. It was not even a month later and the screen started cracking on the one dark spot. I reported this to her and then she told me that they will not repair it again as I previously enquired for a friend about a broken screen quote but different to mine (directly to Laceys) but got it repaired locally and she ended up selling her tablets Oct last year as they kept on giving software issues. Now they got this confused with my tablet which was sent to them in August last year. After providing proof that they broke it TRU still does not want to repair the screen. They asked me for the serial numbers but I only have 1 as my other one had manufacture faults and is with Laceys.
