I have found two law firms for our civil case and both has rejected my case with no reason at all and when i asked why secretary said she does not know so i asked if i meet with attorney she said no.Is this not some kind of discrimination ?

Call the number on the website, they can help you get in touch with someone who can help with this.

It is not discrimination based on the information you provided. You gave no reason for them not taking the case, and like any transaction they have discretion. Many times there may be a conflict of interest, principles or prejudices. For example, some lawyers don't like suing cops or prosecutors if in a past life they were either.
