Claim rejected as wall didn't contain brickforce.

Boundary wall fell over. During the claim process we were advised that the claim will not be covered as the wall was not built to standard as it had no brickforce. There is no way anyone could have known that the wall was not built to some standard sometime in th 1900s. Really concerned that we are paying for home insurance that doesn't cover claims based on findings that we could not have known or foreseen.
