Pathetic Service From Current Hisense Call Desk and Service Team

So I logged a ticket with Hisense for a warranty repair on my 58" TV. At first I got my ticket number 885704 and waited. I called Hisense service desk towards the end of the day and they then advised me they have a 24 hour response window (They don't stick to it). Then I followed up again a day later was advised a tech would be attending within a day or 2 (No tech attended). I called again 2 days later and was told an agent was busy with my ticket and I would have a response within 20 minutes (Again this was BS and I did not get a reply).

Working in the service industry as well I know the challenges faced with such a huge brand and that quick turn around issues are not always possible, but the lack of any feedback and broken every commitment to the customer broken is pathetic.

From what I can gather from other online service manuals and media the error is related to the power board so make sure your tech brings one for the repair.
