Disappointed with my brand Hisense TV response from the Hisense technician not taking a Hisense TV under warranty to fix as they say coco roaches are the problem

Am not happy with their rules while they did not inform us before buying their product my Hisense TV 50 inch is started to give us problems I informed the technician come today early during the day to my surprise he said he is not allowed to take the TV if there is coco roaches. they failed to do the protection for coco roaches not to be near the TV as they knew it may cause the damage.

My question is this one with Hisense is this a way of us loosing our money? from buying our favourite brand? and be treated like this? Now my warranty comes to an end in July 24 and i will no longer have 21 working days so Do I loose like this?As for quote for how much you will fix for me I do not have that money am standing with hope in peace for Hisense to come up with a solution for this
