Hi Bullet
Welcome to the forum.
You might want to have a look at the following FAQ which explains where everything is;
www.benefitsandwork.co.uk/guides-for-claimants/faq/forum .
Things do happen when you are in panic mode, you need to contact DWP and ask for a copy of the assessors report called a PA4,, once you get the report go through it carefully with a highlighter, highlighting any inaccuracies , if you are quick you may be able to write to the decision maker pointing out the errors before a decision is made. Make sure in your letter you are not requesting a mandatory reconsideration but reserve the right to do so once a decision has been made.
