Misleading services

I have been waiting for Makro customer services to contact me since Friday!! We walked in with the intention of purshasing the Sinotec 50" Android tv. After discussing it with the salesman and looking at other options, we settled on the 55" Sinotec smart led tv. As advised by the salesman this was supposed to function exactly the same as it has android built in as well. Immediately after using the television we were extremely unimpressed and it did not function as promised. Furthermore there are apps that will not work because the device is not certified. The application to mirror is from an unreliable source and warnings pop up. We tried long and hard to make the mouse work only to realise after my sister bought the exact same tv in a 43" that there is a part missing. The remote is absolute **** and constantly jams. This is the second time that I have purchased from Makro where I have been misled by the salesman. We took it lightly with the Ps4, but I feel this time the lack of customer service from Makro needs to be heard. I need this complaint resolved immediately and I am not willing to settle for just an apology this time around!
