Hisense - A shocking tale of poor communication and service delivery

I really dislike writing a review on such platforms, but I feel I am left with very little to no choice.

I have had a black line run across my B7100 Hisense SMART LED since the weekend. I have tried calling Hisense from Monday already to get a service technician to my home as it is still within the 4 year warranty.

Alas, there appears to be no one working for Hisense.... Monday I called the service centre no one answers the phone. Tuesday I call, no answer, Wednesday I call, no answer and eventually out of sheer desperation I called Hifi Corp on Wednesday and a nice lady there gave me a direct email contact for someone in the credits department. I sent her my proof of purchase and images of the problem only then, did I get a call from Thuli to whom as patiently as possible I explained my plight. I explained to her that I cannot have anyone come to my home in the afternoon as I am office bound, so she called me back to explain the technician will come at 6pm after there "appointment" with Hifi corp today Thursday......it is now 7pm, no phone call, no sign of any technician calling me on my cell phone for an update....this is a new low for any companies service delivery much less a company whos TV's are the "number 1" selling tv in the country.

I want my credit from Hisense with respect to my warranty and I promise now I will never ever have another Hisense product pass through my doors again just based on poor to zero communication...I miss their technician Jerome who I sadly found out left the company.

I expect answers soon.
