they said that even though they know that I didn't do anything they are still going to terminated me because they said that they can no longer trust me.
What your saying does not make sense- if they are being genuine in their reason for terminating you. You should ask for your employment file and contact some employment lawyers in your area to go over the facts to determine whether or not you have an action.
This is my opinion and should not be construed as legal advise for your specific case as there are many more facts which you have not provided.
