Horrible experience and Service

Had the most horrible experience with Hisense South Africa, had issues with my TV, it was taken for repairs and was gone for 5 days, the device came back and it was not repaired and came back in the same state as what it left. Getting through to the service line is an absolute nightmare, speak to 3 different people and get told "I am calling the technician now" and they rather end the call. We were then told it was going to be escalated to the head office, this was last week Friday. We have still not received the email follow up we were promised, got a contact number for someone to assist us and they are not even aware of the escalation and just not getting back to us. Can someone please get back to me about this!
