Hisense South Africa - NO SERVICE

I called the following numbers numerously, without an answer: ***3 (Support) *** (Service Centre CPT) *** (Service Centre JHB) ***

I emailed the following without response: *** ***

I tried getting assistance from the Omni Chatbot without success.

I send a private message on FB messenger without a response.

What do I have to do to get service from Hisense South Africa???
