Complete disrespect and lack of care for customer goods

I have not words for Game store in Chris Hani mall. I took my Hisense tv to them for repairs as according to my understanding it was still under warranty of 4 years. My tv only had 1 problem “the display was showing dimmed images and there no backlight on the screen”. The time I took it in they checked and confirmed that the tv display does not show clear images and there was no crack picked on the screen. To my surprise I received a phone call from the store after 4 weeks alerting me that the manufacturer says the tv is out of warranty and that the screen is cracked.. That is one of the many reasons i was given - the one before was that the panel need to be replaced etc. However today I went to collect the broken tv and it was wrapped with a box and bubble plastic, the corners of the wrapping were badly torn and that is proof enough that the handling was bad. When I got home I unwrapped the tv I discovered a huge dent “crack” on the side of the screen which was never there before. When I was still in the store I tried to speak to the lady at customer care and she could not explain what the issue was then I asked for the manager “Martin Ntlanzi” and he also made it clear to me that he cannot offer me any assistance whatsoever. I have never felt so disrespected and completely helpless. If they could not repair my tv because it is out of warranty then why damage the tv even further? There’s scratched all over the my tv. Game store in Chris Hani mall is a big joke and they have no regard for customers. I mean I drove from my house in Akasia in Pretoria to Chris Hani mall about 93.1 Km to receive such disrespect? I am going to pursue this matter to the bitter end because i want my tv in the same condition it was brought in.
