My boundary wall.

Auto & General has done it again, submitted a claim for my boundary wall that has collapsed, when I bought a property I find the boundary wall, they opted to be my insurance, now I submit a claim i'm being told that my wall was too high does not have reinforced iron as if I build the wall, they refused to fix it, always I must look for them, they don't even sent follow up sms to show concern. all my 3 claims was rejected with poor reasoning. They don't deserve to be still doing business and my rating for them is zero they don't deserve even single star
