Return warranty product in terrible state

On the 30th of November I used my Hisense warranty as there was black shadow type markings on my 70” display. They collected my tv on 30th as well. On the 8th of December I got contact that my tv was completed, but the tV was never delivered as it was sitting with technicians for dispatch. Eventually on the 16th of December my TV was returned after contacting them regularly. My TV was returned with scratches and frame damage on the left side top right corner. On the display there is two parallel lines across the display, in the bottom corner there is a black shadow type marking and also there is a visible scratch on the top right display on the inner part of the TV. The driver who delivered said it wasn’t them and it was the service centre and wrote that on the job card. I contacted hisense on the 17th of December and since then they are impossible to get hold of and give feedback. I was told that a technician will come to me to do a report on the TV and it will be taken from there. The technician has not come to my property which is about 10 minutes away from service centre. Everyday I have contacted Hisense and was told the tech is coming he just got caught up. The past three days have been exactly that. I find it highly unacceptable that Hisense return a TV in a horrible state and on top of it they won’t take ownership or assist the customer that THEY have inconvenienced. I do not recommend dealing with hisense service centre as they appear not to know how to deal with their customers. Especially for a 70” TV.
