Unfortunately, without the additional information requested in my first/previous response, I will not be able to give you detailed advice to your question, but I will be able to give you a general answer, which I hope will be of assistance. If you are able to supply the additional information later, please do so and I will then come back to you with a more detailed answer.
I can gain form your comments above that you have been dismissed from work, but do not expand why.
If the employer has failed to follow correct procedures in your dismissal, you may have a case to take to an employment tribunal. Likewise, if you have been with them more than 2 years then you may also have a case for unfair dismissal.
You can seek further advice and help with this with acas, they can be reached at www.acas.org.uk
In the meantime, if you would like to supply me with more detailed information then I may be able to give you more detailed advise.
