What a disgrace of a company (Old Mutual Insure)

WORST SERVICE I was informed a week ago that my claim for a wall that collapsed during a storm was rejected due to it not being an insured peril. I have comprehensive buildings cover and surely it must be an insured peril if a wall collapses during a flood and storm. I have been waiting since 23 December for them to send me a rejection letter stating why my claim was rejected. Since submitting the claim on the 9th of December the only call i ever received was on the 23rd to says your claim has been rejected. This is not service. This is an utter disgrace of a company.
