I suspect ***** on my claim by Discovery Insure

In August I claimed for my television that broke due to water damage from rain, we had 2 sets of rainfall in August and experienced a terrible roof leak which caused water damage to the television. Discovery sent Anthony their assessor to inspect my television at my home and Samsung technicians where after I got a call from Anthony that my claim is rejected do to them NOT finding any water damage. They claimed that my television is just "old" although it was purchased end of 2020. I was unhappy with the outcome and did not dispute because as Anthony told me there is no use to dispute since that is their outcome from Samsung. In October a family member suggested I contact Teleshaw to try and fix my television, since it is just "old" maybe they are able enough to fix it. Teleshaw contacted me and their outcome was, that there was in fact water damage which is very clear on their findings and therefor can't fix the television. I contacted Ashley and shared my disgust and the information, he requested I send him the report from Teleshaw which I did on 27 October, I had since not heard from him, he is avoiding my calls. To me this is *****. Teleshaw insured me that the water damage is very clear should have easily been traced by Samsung. I have never skipped premiums on my insurance but they refuse to replace my television. How many people out there accept the outcome because they trust there insurance company. I did try to dispute this after I got the report from Teleshaw but Discovery say it's too late, you should dispute within 30 days. I did not dispute because I accepted the outcome, it just so happened by chance that someone referred me to Teleshaw because of their great reputation to fix my "old" television that is only 5 years old and only then did I learn that my television does in fact have WATER DAMAGE. Do they do this on purpose to avoid paying out claims??? How many people like me just accept an outcome because we do not know better? Why have I not receive a call from Discovery regarding my claim and the new report from Teleshaw? Why is Discovery hoping I will just go away by avoiding my emails and calls???
