Beware of Preinstalled Apps from Hisense that don't work!

It's almost a month now with back and forth emails with Hisense and it's technical team. I bought a TV that was meant to have preinstalled Apps that function optimally. I raised my concerns with Hisense and was told my software needed to be updated - we did a few tests and a few software updates. Still the App didn't work. My TV was collected to check for technical issues - its been over a week now and still i am not receiving any communication. Every time i call i get told my TV will get delivered on the day, i've had to miss going to work just to make sure i am at home when the TV is delivered. I've skipped 5 days'and pending!!!
