how to collect my money that my company never paid me

I started working for a company in april. They said that they were highering me for full time at $10 an hour. At the end of may my drivers license was suspended due to my disability. I lived 35 minutes from my work so finding rides to an from work was extremely hard. I had 2 days a week that I had gurenteed transportation, and told my manager that I could possibly work more if they gave me a schedule far in advance. They said that they would work with me. About a month later and them only scheduling me at most 1 day a week, if any, I went into work and they said that they hired a replacement and they could not work with me if I could only work 1 day a week. (That confused me since I was available 2+ days a week) and they gave me my final check before I left. When I was looking at the pay stub I noticed that my hourly wage was $9. So for my 200 hours I worked I was shorted $1. And they back doored me due to my disability of diabetes. I called them to get my money they did not pay me and found my contract stating my wages. They called me back stating that they did not owe me since I did not carry out my duties. How can I get what I deserve when all my coworkers made $1 more than I did and my contract states it as well? I do not want to deal with my managers crap and would like to deal with someone else or have maybe a lawyer represent me. I think I can take them for my pay cut and for being discriminatory toward me
