AIM SMART TV - NOT SMART AT ALL!!!

We purchased an AIM 55' SMART TV from your Hyper By The Sea branch in December 2017. In 2018 we had taken out a LTE contract to make use of the pre-installed Netflix App to stream movies and make use of the TVs SMART features. The TV freezes, closes the applications and switches itself on/off. We complained in Sept 2018, we were told to send through an email with our complaint and a copy of the slip to which we got no feedback. We sent another request in July 2019, this time we were told the TV has a software problem they will contact me shortly with a solution. I was also told that the device was not intended for the Netflix App which came pre-installed together with other apps. A month has gone by and we are nowhere close to a solution. We have taken out a 100GB per month contract just to utilise the TV capabilities. It makes no sense buying a smart tv and buying an android box just to stream movies. We feel mislead as other smart tvs of other brands seems to work perfectly fine with Netflix and other streaming Apps. We are very disappointed with the product together with the after sales support received.
