dwp dont listen to the law (Disability and the Equality Act 2010)

I can not read, or write very well, as I am dyslexic, so sending letters to the DWP is very hard. I cannot appeal their descions without help, and the DWP won't give help to people with dyslexia. I have tried to contact Ian Duncan Smith,(Secretary of State for Work and Pensions). I have called his office, and no one replies. am unsure how things are in the UK, and I dont know what this means?>>>>>>>>to try and change this people that work as mp work for people who live in the uk i watch a progam on bbc about parking and it was put to the vote cause it was the mp s kid got a ticket so he took it to the houses of lords but i dont get the same when i compain to please sign up
