What do you do when your Senator/Congressman doesn't help?

First of all I am not a Democrat nor a Republican; I am a registerd "American Independent." I went through a stream of racist tactics while enlist with the Arizona National Guard - Unfair treatment against was recorded. I go through many channels without resolve, my congressman Rep. Jeff Flake and Congressman McCain's bureau; However when it came to an issue of "Racism" they chose not to fight for me. My issue was confirmed. I official a position with the Arizona National Guard after a telephonic interview. Upon my arrival my pay was dropped 2 steps and adjectives I was told was that it was a "mistake." It be a great dissapointment esp. after leaving a higher paying job. I go through a series of desparative treatment. I am very surprised these two individuals could not help, what can be done if they are not doing anything?
1) Do not vote for them, contained by the next election.
2) You may still find some kindred soul who will take up your result in.
3) You may fight it legally. Move the court, if advised by an attorney.
I would research the ways to bring back them out of office. Ex. Find out if you need a petition with signatures and who to move about thru to help with the matter.

You could also not vote for them anymore.
Vote against them in the subsequent election and campaign for their opponents.
