False advertising

Recently bought a AIM 55 inch Smart TV 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? This after the salesmen tells me I just need to update the app! I can't do that, nor can I stream through the browser! Pathetic!
