I need to make a serious complaint about the headmaster at my childrens school , in legal terms he has committed perjury , in plain old terms he has lied to either my face or to social services , I have proof of this in writing where he has plainly contradicted himself and also has , as i said before lied to my face , please can someone point me in the right direction as i want to make a complaint but cannot find out how to do this on the school website , many thanks in advance .
