Letter of Complaint with legal references and citation's

In regards to a housing matter. Due to my severe mental conditions, my G.P and Neurologist wrote clearly to the City of Westminster Housing that I should be provided with permanent social housing which should also be local as my family lives local and I need 24/7 supervision but the housing application caseworker did not taking any medical history into consideration and offered me 3 choices of private property. 2 properties was too far meaning if I was to choose either then I would loose family support and the last one I had to take as it was local and I had no choice and if I did not take 1, they will discharge their duty and I will be left homeless. Having spoken to few solicitors and a barrister, they all aid I have a very strong case as among various breaches of legal rights, they have also breached the Human and Equality Rights. I need a letter of complaint (which I will write) and on that I need research carried out on all the breaches of Law which can be put on the letter o it then can be forwarded to The Housing Ombudsman and need being, take it to Judicial Review.
