Hisense-poor customer service

I purchased a Hisense TV, a 75" smart TV in the region of R25k

Take note of the following facts:

1. The TV has been a problem from the start with regards to the "smart TV " capabilities in that it never worked as a smart TV. I emailed a short while after receiving (you welcome to check the history of emails to verify this) the TV to notify Hisense about this and because I assumed that it could be my internet connection, I never followed up with having a technician come out to assess.

2. Upon having fibre installed, I found out that the TV is still doing the same thing and this is when I contacted Hisense for a repair as my internet connection was never the problem.

3. I was let down constantly by the technicians where I even took leave to be available for a technician and they never showed up AND never take my calls.

4. Eventually when an appointment was made and they did show up, they agreed that the TV did have a problem. They attempted a "reset" which did not rectify the fault. They then placed the tv down and took it apart to replace a circuit board.

After fitting this new board, they realised that it also didn't make any difference.

When they mounted the TV back, I noticed a crack across the length of the TV screen. This is definitely unacceptable. I notified customer care about this and they said they will follow up. Since then, all my emails are being ignored and nobody is able to address the problem.

Is this the kind of service offered after spending that kind of cash on a high end product?????
