Poor service delivery from HISENSE

On the 31 May 2023 I logged a fault with Hisense for a TV which was purchased in November 2023. We received a reference no, a technician came out and stated that the motherboard needs to be replaced. I have been calling Hisense they referred me to the company that is responsible for repairing it (East Coast Appliances) they don't even take your calls. We now in June and to date the TV has not been repaired and still no response from Hisense. They stated that the technician will call i am still waiting for their call. Absolutely disguisted with the service from HISENSE.
