Hi Naziaarif
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 .
I've moved your post to its own topic, we ask members not to post their questions in other member's topics as it can lead to the wrong advice being given or taken.
We are unable to help individuals and can only give general advice, you need to contact a local welfare rights organisation to get individual help. 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.
