Bad service!!!!

I've recently put in a claim with King Price on my home content which was my TV that kept going dark after a few seconds when putting it on because rain water went inside due to a roof leak that happened for the first time that day, because I've never had a roof leakage problem before, probably cause it was raining with hail that day i don't know, but my claim was rejected saying that they don't cover consequential loss..and that the TV wouldn't have gotten water if the roof didn't Leak. First dissapointment, because these are one of the reasons we actually cover our home contents, secondly when I called I explained what happened to the TV so they should have said right there that it wasn't covered, instead they send people to come and do an assessment taking my TV away and took a video that showed how my TV was showing at the time they took it, so after my claim was rejected.. I asked for my TV back to fix.. Guess what.. I got my TV back via courier, screen damaged showing black on the one side and couldn't even be repaired.. Now the people send to do an assessment is trying to shift the blame saying that my TV already had defects when they took it.. Just like that King prize accepted the matter as resolved after receiving that feedback from them .. To think I still have my car insured by them.. Nah very dissapointed this time around with King Prize because I've always received an excellent service with my windscreen from them..but if this is what I'm getting with just home content, what about my car...
