Poor Service from Hisense Call Centre

I very disappointed at the Hisense TV 55 inch I bought from takealot.com. I bought the TV on 22 October 2020 and it was delivered on the 24th. On 28 November 2020 it just switched off while playing. On the first December 2020 I logged a ticked with Hisense, ref***. Till today my TV is still dead and no one t Hisense has called me. even after few follow up calls.
