Dear Mr. Fredericks:
We are really sorry to inform you that your claim on house damages dated February 15th has not been approved, following regulations outlined in section D, clause No. 435 of your house insurance policy.
After studying your file and following the inspection our agent Mr. Robert Newhart, performed on your house last January 20th on our premises, he concluded that you were not a victim of an act of vandalism but rather your house was damaged when water from local run-off flooded the basement. This kind of incident is described as "Natural Causes" in section B of your policy on Kinds of Insurance Claims.
I have reviewed your policy, and determined that the type of policy you hold does not cover the damages you have sustained. Unfortunately as
A. Jessica Vanderburg
B. Mr. Alfredson
C. An inspection agent
D. A policy holder
