If you know what’s good for you runaway from Hisense

We have a Hisense smart TV we bought in 2020. It’s starting to be really useless for us. It was first Showmax when the app was upgraded we could no longer watch Showmax from our TV. Despite the calls we logged with Hisense they could not help is with anything. It is now the DSTV now app giving us problems on the TV. What is this TV good for?
