What do I do if I feel I've been discriminated against?

I am on SSDI. I was called for an interview. When I got there I had to fill out an application with my SS#. The interview went really well. I was interviewed for approximately 45 minutes. The manager that interviewed me seemed extremely interested. I had just completed a course in medical claims and billing, which was the position I was interviewed for. At the end of the interview she told me it would be full time and the pay would be $12.00 per hour. I asked her when I would know if I was hired and she told me she just had to talk to her administrater but knew she would be told she could hire me on the spot. From there she gave me a tour of the whole facility and showed me where I would be working. As I was leaving she even stopped me and asked for my cell #. Now she has avoided my call
