I want to take legal action against illegal CSA bailiffs

How does my company take the CSA/DWP to court over illegal baliff action where bailiffs took property from the company premisis (I am a director)where I live. I have had all items now returned. I want to claim against the time taken by directors letters sent. Lose of use of company computer etc. I have told them I want £20,000 + I sent them a list of cost etc. I told the enforcement officers they were acting illegally etc. It took nearly 5months for them to return everything. Which is the best method to take the DWP on?

The company owns a pub it is struggling. I have never taken money etc out. For the last four years I have not even taken a wage. The CSA claim I have earnings etc of £349.61 ! This is not backed up by either the company accountants who keep saying the CSA is acting illegally. HMRC see no income from the pub and so I pay not taxes as an individual to them. If they say I am having an income of this amount why have they not informed the HMRC that I am acting fraudulently? Any advice would be welcome especially any lawyers who might work on a no win no fee line.
