Not replacing TV due to wear and tear

I have been a loyal customer with Alexander Forbes now momentum for the past 17 years. I had an incident where a bird flew into my TV it did not break but since then there has been a halo on the television and I am unable to watch it. They sent an accecor out and they claimed it it wear and tear. I would understand if I have multiple claims over the years however I have not. I am totally disappointed in the service I have received.
