Do you think I can have my job back? Can I be compensated for the time I’ve been to off?

In March of 2017, I was hired in non-degreed position. After six months of being employed, I became eligible for a promotion. I applied for the position and I was selected for the job. Another three months past and I got another premonition. I was in this position for almost a year. The assistant director approached me with questions about a degree. He told me that if I could not provide proof of a bachelors degree, I would be demoted. I went to the HR department the next day to inform them of the situation. I explained to them that I hired in a non-degree position and was promoted to the position I in at the time. I did not lie or falsify anything. A few days later I was terminated for being in a degreed position without a degree. I don’t understand what I did to deserve this.
