I would be careful about cancelling policies after a claim is denied and switching companies. It will probably make your premiums double, if they decide to insure you. Inusurance companies will research past claims, and be hesitant to provide service or the best premium price if they think you will switch after every denied claim.

I would get in contact with the state insurance commissioner. His office helped me a great deal. I had a homeowners claim wrongly denied and the ins. commisioner guided me through resubmitting the claim and it was covered.
