AIM 49 inch Pick N Pay Smart TV

Recently bought a AIM 49 inch Smart TV for R4999.00 with the intention of watching/streaming servives such as Netflix, Showmax, DSTV Now. After numerous attempts to stream such services via the app/browser even mirror cast, an error pop up or sound playing but a blank screen! It is absolutely false advertising as they promise all the bells an whistles on the box however none of these apps work! It even comes pre-loaded with Netflix and it doesnt work? I mean really? If the app store on this TV is unlicenced, why is PicknPay selling it? I now have to cough up more cash to buy an android box to get these functions! Ps: the remote tends to be buggy as well, giving letters which I did not type!
