Hisense Shocking Service

I purchased a Hisense TV in November 2023. In January the screen started deteriorating. I contacted the store where I purchased it from and they proceeded with a warranty claim. I supp**** photos of the damage and was told the technician will not come out to assess the TV because the screen is cracked and therefore not covered by the warranty. I can find no-one to come and have a look at the TV so that they can see that it is in fact not cracked. I am trying to get hold of a Hisense approved technician that can look at the TV and confirm that this screen is not cracked. I am so livid with Hisense, what makes me even more hot under the collar is that I have always supported this company. With the way they are handling this complaint they are losing a loyal customer, but it doesn't seem to phase them, it's not their hard earned money that was spent. All I have so far is a list of Ticket numbers. #***
