Damaged goods received as replacement

I bought 2 Kurio tablets from Toys R Us Mall@Reds. Both tablets started having problems charging so I contacted the store. I have been dealing with Keshan and Percine troughout this time. They contacted the supplier (Laceys) which then also got in contact with me. They asked me to send my tablets to them in Durban. I was told I will have them back in about 7 days. I did this and one of my tablet's screen got damaged in transport by Skynet. They checked the tablet which did not have the broken screen and found it had a faulty motherboard and replaced this tablet with a brand new one. They then replaced the screen on the one that got broken by Skynet and they sent it back with the new tablet. This took them a month. They did not even check it for charging issues. So when I got it back it still did not charge and the screen was loose. I then had to go back to TRU AGAIN and they sent it away again. They then found that the charger itself was faulty and replaced it but the screen is still not as per my original tablet I sent to them. I then wanted to load apps and discovered the new one has a ink line on it and reported it. I have had no further feedback and email them daily.
