It's sounds as if it was a hard exterior to your case, if so then your lid, which I'm sure would be surrounded by padding of clothes etc., to get that badly damaged
. Think, well know that when the claim is settled (always the optimist) get a different make for sure! Doesn't give a huge confidence boost as to how it would hold up to concrete impact whilst your head was encased in it
. Very best of luck
