Hi Garyhiggins100
Welcome to the forum, you might want to have a look at the following FAQ which explains where everything is.
Welcome to Benefits and Work We do not have enough information to give you advice, unfortunately your question is also outside the remit of the forum.
The first thing you need to do is request a mandatory reconsideration, I would advise you to seek help from your local Welfare Rights Organisation who can all your circumstances into consideration and give you accurate advice; you can find your local Welfare Rights Organisation to help you with advice by clicking on the link below and putting in your post code, it will then come up with a MAP with a list of agencies.
