GETBlack Smart Top Box

Good Day, so this is the first time I'm writing one of these. I purchased a GETBlack Smart Top Box about a week and a half ago. The service works perfectly fine on my PC and iPad, but has countless errors on the machine. 1. When I choose a movie it plays immediately (with my Wifi registering a speed of 60mbs), but after about 10 seconds I'm met with a continuous loop of the loading screen (PS I have tried my ethernet cable so don't even mention it please) 2. When I try watching one of the live TV channels, I receive the following error 'the channel is temporarily unavailable'. It never becomes available... This led me to activate the Flexi Premium trial. Still nothing.

I thereafter logged a fault at ********** 1. I was told that the issue will be resolved by my next call back. You guessed it, it wasn't 2. The (now infamous) 'IT department' was then instructed to resolve the issue, which was not done. The call centre then contacted to confirm that the issue was resolved. After informing me that it was not, they instructed the IT department to contact me at a particular. No call was received... 3. After sending a further email to support, which was met with the 'matter will be looked into immediately', no further response was received until I sent another email. 4. I then received another call from someone who was not part of the IT department to run some tests. I had to pay for an additional weekend Flexi Premium plan so that I could 'test' the movie playback from my side. 5. Fast forward to today, I receive another call to schedule a callback from the IT department at 8pm. I have not yet received the call (Also I do not understand with the callback cannot be scheduled via email)

So in summary (and sorry for the long post) I have a machine which thus far I have been unable to use and I'm stuck in a loop of scheduling a callback from the IT department who do not make the call.
