TV app doesn't work, non-existent support.

The Showmax app isn't working on our TV. I had a long discussion with a support person via "chat" on their website. She wasn't able to sort it out and escalated it. She said that the turnaround time would be 48 to 72 hours. It's now been 2 weeks and not a word. I have in the meantime emailed them twice - no response. I just tried following-up with them via their Facebook page but she can't do anything with the support ticket reference number, saying "we are unable to track down tickets done via live chat" and wanted me to repeat the whole story all over again. Luckily I kept the transcript and sent it through. He/she couldn't assist either - just escalated the issue again. So I will probably again not hear anything back from them again. USELESS!
