Disappointed in the Hisense “customer support” team

I purchased a Hisense TV less than three months ago and it has stopped working out of nowhere. Logged a query with their customer support on 7 June 2021 and until now, no one has come out to look at the tv to identify the issue and to repair or replace. This shows a complete lack of regard to their customer’s issues. So much for customer support. And why sell a tv that’s clearly not up to standard? Overall disgusted and disappointed so far with the way the matter is being handled. Also noticed that they don’t even bother to reply to complaints on HP.
